I am hoping that I can get some help at reviewing the data below (it would be great if you had feedback if the data in the results area is correct) and helping me answer the following questions:
Use the contingency table to determine if there is evidence of a significant difference between proportions of males and females who enjoy shopping for clothing at the 0.01 level of significance?
Determine the p-value in (a) and interpret its meaning?
What is the null hypotheses?
Homework Answers
Null Hypotheses is denoted by H0.
H0 : There is no significant difference between proportions of males and females who enjoy shopping for clothing.
since
In inferential statistics, the null hypothesis is a general statement or default position that there is no relationship between two measured phenomena, or no association among groups

Hello! I am hoping that someone can provide me with an example for this question. I am supposed to write a confidence interval problem (not solve it) using this option-- "Think about a population mean that you may be interested in and propose a confidence interval problem for this parameter. Your data values should be approximately normal. For example, you may want to estimate the population mean number of times that adults go out for dinner each week. Your data...
