Suppose that the biologist tests the following hypothesis:Но : р — 0.25 vs. HA :р> 0.25Where p is the true population proportion of Black Carp in Lake Huron. Of 200 randomly sampled fish from Lake Huron, the biologist finds that 18% are Black Carp. Select from the followingoptions the correct z-score and P-value associated with this hypothesis test.Select one:O a.z =-2.58 ; P-value = 0.9951Ob.The hypothesis test cannot be performed because requisite assumptions have not been satisfied.O c. z =-2.29 ; P-value = 0.9890O d. z =-2.29 ; P-value = 0.0110O e. z =-2.58 ; P-value = 0.0049

Given that Then we have to find z score and p value:

A study of the career plans of young women and men sent questionnaires to 722 students of class at one University. One question asked which major within the business program the student had chosen. With data we test a statement: Does the data suggest that there is a relationship between the gender of students and their choice of major? We calculated the p-value and it is 0,0127 and the level of significance is 0,05. The conclusion to the test is: a. there is sufficient evidence to conclude that the choice of major and the gender of the student are not independent of each other. b. there is insufficient evidence to conclude that more females prefer administration than males c. there is insufficient evidence to conclude that the choice of major and the gender of the student are not independent of each other. d. there is sufficient evidence to conclude that students find economics very hard.

According to previous studies, the mean distance each visitor in Greenspan National Park hikes during their visit is 30 kilometers. The park recently closed its shuttle system, which used to transport hikers to many of the park's most popular hiking trails. Because of this, an administrator at the park suspects the mean distance, u, is now less than 30 kilometers. The administrator chooses a random sample of 45 visitors. The mean distance hiked for the sample is 27.2 kilometers. Assume the population standard deviation is 9.9 kilometers. Can the administrator conclude that the mean distance hiked by each visitor is now less than 30 kilometers? Perform a hypothesis test, using the 0.10 level of significance. (a) State the null hypothesis H, and the alternative hYpothesis H,. O
