Thank you so much! Before the furniture store began its ad campaign, it averaged 213 customers per day. The manager isinvestigating if the average has changed since the ad came out. The data for the 12 randomly selected dayssince the ad campaign began is shown below:197, 211, 228, 226, 188, 216, 183, 204, 219, 203, 206, 196Assuming that the distribution is normal, what can be concluded at the a = 0.10 level of significance?a. For this study, we should use t-test for a population meanb. The null and alternative hypotheses would be:Ho:?vSelect an answer ♥H1:?v Select an answervc. The test statistic ?v =(please show your answer to 3 decimal places.)d. The p-value =(Please show your answer to 4 decimal places.)e. The p-value is ? vaf. Based on this, we should Select an answer v the null hypothesis.g. Thus, the final conclusion is that ...O The data suggest that the population mean number of customers since the ad campaign beganis not significantly different from 213 at a = 0.10, so there is insufficient evidence to concludethat the population mean number of customers since the ad campaign began is different from213.%DO The data suggest the population mean is not significantly different from 213 at a =there is sufficient evidence to conclude that the population mean number of customers sincethe ad campaign began is equal to 213.0.10, soO The data suggest the populaton mean is significantly different from 213 at a = 0.10, so thereis sufficient evidence to conclude that the population mean number of customers since the adcampaign began is different from 213. h. Interpret the p-value in the context of the study.O If the population mean number of customers since the ad campaign began is 213 and if youcollect data for another 12 days since the ad campaign began, then there would be a13.6962465% chance that the population mean would either be less than 206.4 or greater than219.6.If the population mean number of customers since the ad campaign began is 213 and if youcollect data for another 12 days since the ad campaign began, then there would be a13.6962465% chance that the sample mean for these 12 days would either be less than 206.4 orgreater than 219.6.There is a 13.6962465% chance that the population mean number of customers since the adcampaign began is not equal to 213.O There is a 13.6962465% chance of a Type I error.i.
