#4 COLLEGE INC., OLONGAPO CITYIGH SCHOOL-BASIC EDUCATION DEPARTMENT ASINANLEARNER'S MODULEName of the StudentSection:Assessment # 2Type of Assessment: Written WorksTarget MELCS: Formulates the appropriate null and alternative hypotheses on a populationproportion, identifies the appropriate form of the test-statistic when the Central Limit Theorem isto be used, identifies the appropriate rejection region for a given level of significance when theCentral Limit Theorem is to be used, computes for the test-statistic value (population proportion),and draws conclusion about the population proportion based on the test-statistic value and therejection region.Date of submission: May 12, 2022Carry out a test of hypothesis to draw conclusions in relation to each of the following problems.1. Previous evidence show that majority of the students are happy and contented with theuniversity's policies. This year, a random sample of 100 students was drawn. They were asked ifthey were happy and contented with the university's policies. Out of 100 students, 65 said so. Whatconclusions could be made at 10% level of significance?2. An independent research group is interested to show that the percentage of babies deliveredthrough Cesarian Section is decreasing. For the past years, 20% of the babies were deliveredthrough Cesarian Section. The research group randomly inspects the medical records of 144 birthsand finds that 25 of the births were by Cesarian Section. Can the research group conclude that thepercent of births by Cesarian Section has decreased at 5% level of significance?3. Ina test of Ho: µ = 85 against Ha: u > 85, the sample data yield the sample statistic z=1.64. Findthe p-value for the test.4. In a test of Ho: µ = 80 against Ha: µ # 80, a sample of observations had a mean and standarddeviation s = 4.1. Find the p-value for the test.

In a recent statewide election, 45% of the voters rejected a proposal to institute a state lottery. In a random sample of 250 urban precincts, 47% of the voters rejected the proposal. We wonder if the difference is significant. a) Evaluate assumptions if we can use a t-test and summarize parameters and statistics. b) State the null hypothesis (i.e., H0) and the working hypothesis (i.e., H1). c) Establish the critical region for t-distributions at α=0.05 with a two-tailed test. d) Compute the test statistics (i.e., tobtained) and the corresponding probability (i.e., pvalue). e) Make a decision and interpret test results.

A law enforcement agent believes that more than 88% of the drivers stopped on Saturday nights for speeding are under the influence of alcohol. A sample of 60 drivers who were stopped for speeding on a Saturday night were taken and 54 of the drivers in the sample were under the influence of alcohol.

A lecturer claims that their course is not too easy and that on average, students score 60%. We want to verify this claim by performing a single tailed test with the null hypothesis μ=60% vs the hypothesis μ>60%. For this, we take a random sample of 50 students.Decide on the appropriate test statistic and compute the corresponding (positive) bound of the critical region for a single tailed test at the 98% level. Give the result to four decimal places.
