Question

Help with entire question please. The last selections in part a) are "treatment or control"

the last two selections for part b) are " reject, or do not reject" for the last one they are "greater than, was the same as, was less than, or was different from"

A study reported the results of a randomized trial of whole-body hypothermia (cooling) for neonatal hypoxic-ischemic encephalopathy (brain problems in babies due to lack of oxygen). Twenty-five of the 93 infants randomly assigned to hypothermia died and 41 of the 93
infants in the control group died. Complete parts (a) and (b) below.
a. Find and compare the sample percentages that died for these two groups.
The percentage of babies in the treatment group that died was %.
(Type an integer or decimal rounded to two decimal places as needed.)
The percentage of babies in the control group that died was %.
(Type an integer or decimal rounded to two decimal places as needed.)
The death rate was greater for babies in the
group.
b. Test the hypothesis that the death rate was less for those treated with hypothermia at a 0.05 significance level. Let p, represent the proportion of babies with these problems that would die after receiving hypothermia treatment and let p, represent the proportion of
babies with these problems that would die without treatment. Write the hypotheses for the test.
