Week 7 Assignment Hypothesis Test For The Mean-Polution Standard Deviation Known

Week 7 Assignment Hypothesis Test for the mean-Polution Standard Deviation knownCompute the value of the test statistic (z-value) for a hypothesis test for one population mean with a known standard deviationQuestionJamie, a bowler, claims that her bowling score is less than 168 points, on average. Several of her teammates do not believe her, so she decides to do a hypothesis test, at a 1% significance level, to persuade them. She bowls 17 games. The mean score of the sample games is 155 points. Jamie knows from experience that the standard deviation for her bowling score is 19 points. H 0 : 168 ; H a : 0.35 , which is a right-tailed test.H 0 : p =0.5 ; H a : p 0.05 significance level So, we failed to reject the null hypothesis Ho And At the 5% significance level, the data do not provide sufficient evidence toconclude the true proportion of odds is different than 50%.Identify the null and alternative hypothesesQuestionA politician claims that at least 68% of voters support a decrease in taxes. A groupof researchers are trying to show that this is not the case. Identify the researchers' null hypothesis, H 0 , and the alternative hypothesis,
