A furniture store claims that a specially ordered product will take, on average, µ = 28 days (4 weeks) to arrive. The standard deviation of these waiting times is8 days. We suspect that the special orders are taking longer than this. To test this suspicion, we track a random sample of 70 special orders and find that theorders took a mean of 29 days to arrive. Can we conclude at the 0.10 level of significance that the mean waiting time on special orders at this furniture storeexceeds 28 days?Perform a one-tailed test. Then complete the parts below.Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.)(a) State the null hypothesis Ho and the alternative hypothesis H.H, :区H :(b) Determine the type of test statistic to use.ローロ(Choose one) ▼(c) Find the value of the test statistic.

After you have clicked the tab for your selected topic and read the problem, answer the questions below. (a) Use SALT to summarize the data. Enter the sample size, number of success, and sample proportion, p for the data, rounded to three decimal places. Sample size Number Successes 4129 1938 0.4691 (b) Write the hypotheses to investigate the research question about the proportion, p, of successes. (Enter != for # as needed.) Ho: 0.4691 H: 0.05 (c) We need to verify the assumptions for using a z-test for a single proportion to analyze this dataset. the population of interest or the sample is The first assumption states the sample is a random sample selected in a way that should result in a representative sample. Based on what you know about how this sample was collected, the sample is a random sample from the populations of interest. The second assumption requires the sample to be large enough to be reasonably sure that the sampling distribution will be at least approximately normal.…

Describe type I and type II errors for a hypothesis test of the indicated claim. A furniture store claims that at least 40% of its new customers will return to buy their next piece of furniture. Describe the type I error. Choose the correct answer below. OA. A type I error will occur when the actual proportion of new customers who return to buy their next piece of furniture is at least 0.40, but you fail to reject Ho: p20.40. OB. A type I error will occur when the actual proportion of new customers who return to buy their next piece furniture is at least 0.40, but you reject Ho: p20.40. OC. A type I error will occur when the actual proportion of new customers who return to buy their next piece of furniture is no more than 0.40, but you reject Ho: p ≤ 0.40. OD. A type I error will occur when the actual proportion of new customers who return to buy their next piece f furniture is no more than 0.40, but you fail to reject Ho: p ≤0.40.

In the twentieth century, it was a common practice in Southern California for houses to be built with pools in the backyard. For new homes, however, that practice may be changing, possibly as a measure to help reduce climate change. A recent study examined a random sample of 171 houses built in Southern California in the twentieth century and an independent, random sample of 75 new houses built in Southern California. The sample of twentieth century houses contained 76 houses with pools, and the sample of new houses contained 30 houses with pools. Based on this survey, can we conclude, at the 0.01 level of significance, that the proportion p, of all Southern California twentieth century houses that were built with pools is greater than the proportion p, of all new Southern California houses that were built with pools? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the…
