11% of all college students volunteer their time. Is the percentage of college students who are volunteersdifferent for students receiving financial aid? Of the 367 randomly selected students who receive financialaid, 26 of them volunteered their time. What can be concluded at the a = 0.05 level of significance?a. For this study, we should use z-test for a population proportion vb. The null and alternative hypotheses would be:Но: руSelect an answer v(please enter a decimal)H1: pvSelect an answer v(Please enter a decimal)c. The test statistic z v(please show your answer to 3 decimal places.)d. The p-value =(Please show your answer to 4 decimal places.)e. The p-value is svV af. Based on this, we should Select an answer v the null hypothesis.g. Thus, the final conclusion is that ...O The data suggest the populaton proportion is significantly different from 11% at = 0.05, sothere is sufficient evidence to conclude that the percentage of financial aid recipients whovolunteer is different from 11%.O The data suggest the population proportion is not significantly different from 11% at a = 0.05,so there is sufficient evidence to conclude that the percentage of financial aid recipients whovolunteer is equal to 11%.O The data suggest the population proportion is not significantly different from 11% at a = 0.05,so there is insufficient evidence to conclude that the percentage of financial aid recipientswho volunteer is different from 11%.

Suppose we are interested in the relationship between individuals’ place of residence (rural versus urban) and their political affiliation (Republican versus Democrat). A random sample of 100 individuals yields the following crosstabulation: Political Affiliation Place of Residence Republican Democrat Rural 21 29 Urban 14 36 a) In words, what is the null hypothesis to be tested? b) Is the relationship between place of residence and political affiliation statistically significant at the .05 level? (Be sure to show the statistics that lead to your decision.) c) Compute and interpret an appropriate measure of association for the relationship between these two variables.

In a food preference experiment, 80 lizards were given the opportunity to choose to eat one of three different species of insects. The results showed that 33 of the lizards chose species A 12 chose species B, and 35 chose species C. They conducted a Chi-squared analysis to test for equal preference. What are the Null and Alternate hypotheses for this test? Clearly label your answers as HO or H1. (Do not use a numerical format.
