The worldwide market share for the Chrome web browser was 69.52 % in March 2019.
Suppose that you decide to select a sample of 100 students at your university and you find that 60 use the Chrome web browser.
a. Use the six-step p-value approach to determine whether the re is evidence that the market share for the Chrome web browser at you r university is less than the worldwide market s hare of 69.52%. (Use the 0.05 level of significance.)
b. Suppose that the sample size is n = 600, and you find that 60% of the sample of students at your university (3 60 out of 600) use the Chrome web browser. Use the six -step p-value approach to try to determine whether there is evidence that the market share for the Chrome web browser at your university is greater than the worldwide market share of 69.52%. (Use the 0.05 level of significance .)
c. Discuss the effect that sample size has on hypo thesis testing.
d. What do yo u think are your chances of rejecting any null hypothesis concerning a population proportion if a sample size of n = 20 is used?
