HW9Q14P2PLS ALSO FIND THE NULL ANALYSIS/HYPOTHESES, PVALUE, ZSCORE, AND THE SAMPLE PROPORTION THANK YOU! In a previous nationwide poll of a large country, 46% of adults with children under the age of 18 reported thattheir family ate dinner together seven nights a week. Suppose that, in a more recent poll, 1097 adults withchildren under the age of 18 were selected at random and 483 of the 1097 adults reported that their family atedinner together seven nights a week. Is there sufficient evidence that the proportion of families with childrenunder the age of 18 who eat dinner together seven nights a week has decreased? Use the a = 0.05 significancelevel.Assume that the population is large and the sample is obtained randomly. Because npo (1- Po10and the sample size is5% of the population size, the requirements for testing the hypothesissatisfied.(Round to one decimal place as needed.)

The random variable X follows normal distribution. We have to test whether the proportion of…

The 2x5 table below shows the results of a random sample of 2200 adults classified by 2 variables: gender and preferred way to eat ice cream. At the 5% significance level, test the claim that the two variables are independent. Your solution must include the claim, the null and alternate hypothesis, your test statistic, the degrees of freedom, the p-value, your decision, and the interpretation of your decision as it relates to the claim. Calculate the chi-square test statistic by hand and show all work

We want to investigate an application performances of IOS and ANDROID operating systems. We selected 10 IOS and 10 ANDROID phones randomly and tested whether IOS phones run faster the application or not. We found t statistics by INDEPENDENT SAMPLE T TEST as 1.634. What are the H0 and Ha for this question? IOS phones runs faster the application than ANDROID phones? Why?
Using the dotplot and the proportion of winners in the store owner's sample, is there convincing evidence that the manufacturer's claim is wrong? A manufacturer of bottled tea runs a promotion in which consumers can win a free bottle of tea if the cap of the bottle says "Winner." The manufacturer claims that 1 in 5 bottles is a winner. A store owner Yes, because a proportion of 0.4 or more occurred 25 out of 100 times, the sample proportion of notices that several of the first bottles of tea sold were winners. Suspecting the manufacturer's claim is false, the store owner decides to randomly select 10 bottles of tea from the next shipment from the manufacturer. She is again surprised when 4 of the bottles are winners is statistically significant and there is convincing evidence that the manufacturer's claim is false. Yes, because a proportion of 0.4 or less occurred 75 out of 100 times, the sample proportion of winners. Assuming the manufacturer's claim is true, she simulates 100 values…

You suspect that drivers for Uber/Lyft have newer cars than a driver who doesn’t drive for Uber/Lyft. Listed below are the ages of cars that you randomly sampled from the streets of Portland. If one were to conduct a hypothesis test for the difference in mean car age and mean Uber/Lyft car age, the conditions for the test would need to be checked. What conditions should you check? Check the conditions and explain how the conditions are met or not. What is the appropriate test to conduct, an independent samples t test or paired t test? Explain. Uber/Lyft car age 4 0 8 11 14 3 4 4 3 5 8 3 3 7 4 6 6 1 8 2 15 11 4 Non-Uber/Lyft Car age 8 8 0 3 8 4 3 3 6 11 7 7 6 9 5 10 8 4 3 4
