Is there a difference in fruit consumption between males and females?

A researcher decided to put this hypothesis to the test. She surveyed a sample of 91 students in PH167 Fall 2021 and obtained information on their fruit consumption. Determine whether the proportion of females consuming 2 or more fruits a day is significantly different from that of males.

Sex	Consumed 2+ servings of fruit?		Total
	Yes	No
Female	50	26	76
Male	7	8	15

Is the proportion of females consuming 2 or more daily servings of fruit significantly different from males? Use the 95% Confidence Interval to determine this.[Hint: If there is no Difference between p₁and p₂, what should the RR be compared to?] First, what are the null and alternative hypotheses?

Group of answer choices

RR =1; RR #1

RR =0 ; RR #0

IPD =1; IPD #1

IPD =0; IPD >1

Calculate a 95% confidence interval for the prevalence ratio as described in Question 30 above[Hint, first calculate the 95% CI for Ln PR (use the 95% CI for Ln RR)]
