A popular blog reports that 60% of college students log in to Instagram on a daily basis. The Dean of Students at a certain university thinks that the proportion may be different at her university. She polls a simple random sample of 253 students, and 168 of them report that they log in to Instagram daily. Can you conclude that the proportion of students who log in to Instagram daily differs from 60%? Use the a = 0.02 level. a. State the null and alternative hypotheses. Ho: p v 0.60 H1 : p V V 0.60O 0 Critical value(s): C] (If there are two critical values, list both values separated by a comma) c. Find the test statistic. D d. Find the pvalue. :1 8- Decide: H0 f. Conclusion: At a = 0.02 significance level, there enough evidence to conclude that the proportion of students who log in to Instagram daily differs from 60%. g. Type of Error: A error could occur in this problem. The probablity of this error occurring is . We can reduce the probability of this error occurring by
