in the above Fictitious data for caffeine intake on low birth weight babies, looking at the p values, and use alpha = .05

looking at drinking 1-150 mg of coffee per day, should we accept or reject the null hypothesis?
accept the null hypothesis
in the above Fictitious data for caffeine intake on low birth weight babies, looking at the p values, and use alpha = .05

looking at drinking 151-300 mg of coffee per day, should we accept or reject the null hypothesis?
reject the null hypothesis because .04 is less than .05 (our alpha)
in the above Fictitious data for ethnicity on low birth weight babies, looking at the p values, and use alpha = .05

looking at nonwhite ethnicity:

1. what is the null hypothesis
2. do we accept or reject the null hypothesis?
1. being nonwhite does not contribute to low birthrate babies
2. reject the null hypothesis
in the above Fictitious data for caffeine intake on low birth weight babies, looking at the confidence intervals:

look at >=300 mg coffee per day, should we reject or accept the null hypothesis?

and why:
reject

the null hypothesis is outside the confidence interval
in the above Fictitious data for caffeine intake on low birth weight babies, looking at the confidence intervals:

look at 1-150 mg coffee per day, should we reject or accept the null hypothesis?

the null hypothesis is contained in the confidence interval then the null hypothesis is true, accept it. The results are not statistically significant.
