Question

Take your survey data and code the gender question as Male= 0 and Female = 1. Suppose we hypothesize that women are more likely to respond to surveys than men are. Specifically, we believe that more than 55 percent of all respondents are women which equates to the proportion of the gender variable to be greater than 0.55. Test the hypothesis.

Females= 24

Males= 9

Provide the 6 step process of testing the hypothesis.

Present your results and discuss why you rejected or failed to reject the null hypothesis.

Answer #1

Week 5 #2
Take your survey data and code the gender question as Male=0 and
Female=1. Suppose we hypothesize that women are more likely to
respond to surveys than men are. Specifically, we believe that more
than 55 percent of all respondents are women (this equates to the
proportion of the gender variable to be greater than 0.55). Use the
methods learned this week to test this hypothesis.
Make sure you go through the 6-step process of testing the
hypothesis....

According to the National Health and Nutrition Survey (NHANES)
sponsored by the U.S. government, a random sample of 712 males
between 20 and 29 years of age and a random sample of 1,001 males
over the age of 75 were chosen and the weight of each of the males
were recorded (in kg). Do the data provide evidence that the
younger male population weighs more (on average) than the older
male population? Use “Y” for ages 20-29 and “S” for...
