A report claims that 46% of full-time college students are employed while attending college. A recent survey of 60 full-time students at a state university foundthat 26 were employed. Use the five-step p-value approach to hypothesis testing and a 0.10 level of significance to determine whether the proportion of full-timestudents at this state university is different from the national norm of 0.46.Let a be the population proportion. Determine the null hypothesis, Ho, and the alternative hypothesis, H,.Ho: n = 0.46H,:n # 0.46What is the test statistic?ZSTAT = (Round to two decimal places as needed.)%3D

PLEASE HELP WITH THE PROBLEM BELOW Let pm and pf be the respective proportions of male and female white-crowned sparrows that return to their hatching site. We observed that 124 out of 894 males and 70 out of 700 females returned. Does your result agree that there is no difference between the proportions of male and female white-crowned sparrows that return to their hatching site with α = 0.05? Formulate the hypotheses Finish the hypothesis testing and draw your conclusion (use p-value to test the hypotheses)

For the situation described below, state the null hypothesis, Ho, and the alternative hypothesis, H, to be tested. (Enter != for # as needed.) A statistical test is designed to show that the proportionp of defectives has decreased below 0.6%. Ho: 0.6 H: 0.6
Suppose researchers conducted a study to see if the mean body temperature for adultswas different from 98.6 degrees Fahrenheit. For this study, they took a random sampleof 25 healthy adults and found a mean body temperature of 98.2 degrees Fahrenheit forthe sample with a standard deviation of 0.6 degrees. The temperatures of the sampleparticipants were unimodal and symmetric.a. Write the null hypothesis and alternative hypothesis and define your parameter.b. Show that the necessary conditions (Randomization Condition, 10% Condition,Nearly Normal Condition) are satisfied to perform a hypothesis test. Brieflyexplain how each condition is satisfied.c. Perform the hypothesis test and find the P-value. (To show your work: Writedown which calculator you are using and what values you are entering into thecalculator.)d. Is there strong evidence that the mean body temperature is different than 98.6degrees? Briefly explain how you know.
