Weighted mean

123 Street Drive, Somewhere, ST 01234 Hearing Conservation Program Proposal Dear Mr. Smith, Thank you for your inquiry about a hearing conservation program for your company. I’ve provided an outline of a hearing conservation program with OSHA guidelines and costs for you to consider. To clarify some of your questions, the abbreviation of dB stands for decibels, which is how acoustic power is measured. Since the human ear can’t hear all the sounds that may be measured by a sound level meter or dosimeter, we will often add weighting, called A-weighting, to relate the results more accurately to the human ear. When dBs are averaged among the hours of an employee’s 8-hour workday, we call it the 8-hour time-weighted average. We can also calculate a time-weighted average using dBA to be more accurate with our findings. Please read through the provided materials and OSHA 1910.95 document and contact me with any remaining questions. I look forward to working with you & providing a safe sound environment for your employees! Sincerely, OSHA 1910.95(d) A workplace environment must be monitored if employees are exposure to a level of…

Weighted Average Math 123 I have designed an Excel sheet providing information over a Psychology 205. This class was graded by homework 10%, quizzes 10%, papers 25%, midterm 25% and final grade 30%. After all the information of the students was provided, the average in general was solved by using the Excel program. The Excel program solved everything, I just typed in the information that was provided and the equation for the program found the solution. It came to the conclusion, that the…

with significance. For Job Satisfaction (indicated by js), r and r squared results are .215 and .046 respectively. The Adjusted r squared was .039. There was significance as determined by a score of .012. Frequent Supervisor Feedback seems to support Job Satisfaction by nearly 5%, with significance. A look at Organizational Citizenship Behavior (indicated by ocb) data shows r at .196 and r squared at .038. The Adjusted r square is .031. Significance is .023. Frequent Supervisor Feedback seems…

RESULTS AND DISCUSSION The Siphumelele wetland was assessed by 10 participants. All the participants were compared to participant 2 (control), who is a specialist on wetlands and has over 20 years’ experience on working with wetlands. The overall results (indicated in Figure 2 and Figure 3) in this case are the combination of the results from the assessment of the impact on the wetland of land-cover types present within the wetland, and an assessment of the impact on the wetland of land-cover…

Aside from the general issue regarding survey data and their inability to accurately represent reality, there are no overtly obvious issues regarding the measurement or operationalization of this variable. The central independent variable I chose was number of group memberships. The variable was measured by simply asking respondents for the number of groups that they belonged to. The unit of analysis in individuals, and the variable is continuous. The mean is 0.833, indicating that the number…

Through reviewing the minimum, maximum, and range of values I attempted to discern and identify potential coding errors as well as invalid data. The nature and distribution of the values were explored through examining the mean, standard deviation, and variance as well as skewness and kurtosis. For example, the variable Age contained 320 valid cases, with respondents ranging in age from 18 to 35 years. The mean age was 28.02 years with a standard deviation of 4.76 years. Emailtime and Wwwtime…

variation in data, skewed towards younger age group. Further, an appropriate graph for ADULTCT, measured at ratio level, is a histogram which can help us understand the shape of the distribution. The histogram displays that the number of adults in the household is positively skewed, as significant amount of data lies at the lower end of the graph. This signifies that majority of the respondents have two to three adults in the household. Descriptive Analysis We calculated descriptive…

9. RESULTS Table 8: Pre Formulation Study S.NO API CHARACTERISATION RESULTS 1 Physical Appearance a white to slightly pink crystalline powder 2 Melting point 138-148 ºC 3 Bulk density 0.396 gm/ml 4 Tapped Density 0.421 gm/ml 5 Carr’s index/Compressibility index 5.94 6 Hausner’s Ratio 1.063 Conclusion: The value of compressibility index above 25%, 15-25%, less than10% indicates poor flowability, optimum flowability and high flowability respectively. As Efaverinz value is <10 so it exhibits…

Students’ scores will be categorized into one of three benchmark levels: At or Above Benchmark, Below Benchmark, and Well Below Benchmark (Dynamic Measurement Group, 2010). Students who score below the 1st grade benchmark established by DIBELS on both the ORF and the NWF assessments, but are not considered Well Below Benchmark, will be included in the study if they also exhibit elevated inattention. Inattention. First grade teachers will rate students scoring below benchmark scores on the…

gives it a range of different moods, but mainly a ghastly touch. The house is described as a ‘musty darkness’ hints that it is sort of a fog/mist. However it could be that it smell as that's what ‘musty’ means. ‘, silence,’ has commas either side of it making it create pace. Susan Hill uses ‘seething’ making it seem like the air is crowding Arthur. Susan has used a list to create pace also. Tension is sustained in this part of the chapter as it seems that Arthur is walking into a thick foggy…
