The mean number of English courses taken in a two–year time period by male and female college students is believed to be about the same. An experiment is conducted and data are collected from 25 males and 13 females. The males took an average of 4 English courses with a standard deviation of 0.8. The females took an average of 2.5 English courses with a standard deviation of 1.0. Set up a hypothesis test to determine whether this difference is...

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...

1. Large Sample Proportion Problem. A survey was conducted on high school marijuana use. Of the 2266 high school students surveyed, 970 admitted to smoking marijuana at least once.  A study done 10 years earlier estimated that 45% of the students had tried marijuana. We want to conduct a hypothesis test to see if the true proportion of high school students who tried marijuana is now less than 45%.   Use alpha = .01. What is the conclusion for this test? A)Based...
