Question

From a random sample of 60 new games, the mean price for a new game is $51.98. Assume the population has a standard deviation of $47.19. This creates a 95% confidence interval for the population mean of (40.04, 63.92). Does it seem likely that the population mean could be greater than $66? Explain. Choose the correct answer below. A. No, it does not seem likely because $66 is greater than the right endpoint of the confidence interval. B. Yes, it seems likely because $66 is greater than the left endpoint of the confidence interval. C. Yes, it seems likely because $66 is between the endpoints of the confidence interval. D. No, it does not seem likely because $66 is between the endpoints of the confidence interval.

A lunch bar has an average sales amount of $8.53. The manager initiates staff training to try to get them to sell more extras (chips, drinks etc), and after this training, a sample of 53 customers had the following sample statistics: x̄ = 9.14 and s = 2.16 Assume our question of interest is: "is there significant evidence that the mean amount spent by customers has increased?" Calculate the observed value of the test statistic (correct to 2dp). A hypothesis test for a population mean is to be conducted based on a sample of size 25. What is the correct distribution for the test statistic (assume that the population variance is not known)? a. N(0,1), since the sample size is small we need to assume a normal distribution. b. N(0,1), as the sample mean is normal by Central Limit Theorem. c. t25, since the sample size is small, and we need to assume that the population is normally distributed. d. t24, since the sample size is small, and we need to assume that the population is normally distributed. A hypothesis test for a population mean has p-value 0.01. What is the decision at the 2.5% level of significance? a. Since p-value < 0.025, we reject the null hypothesis. b. Since p-value < 0.025, we accept the alternative hypothesis. c. Since p-value < 0.025, we reject the alternative hypothesis. d. Since p-value > 0.025, we fail to reject the null hypothesis.

00:01 Hello, here we have to solve the following problem.
00:02 Sample has a size of 60 items and that is n1.
00:09 Mean of the sample is 90 and the population standard deviation sigma is 15.
00:19 First in question a we have to find 95 confidence interval.
00:29 Let's do this.
00:31 So here this confidence interval can be found as following that is mean plus minus t coefficient times sigma over square root of n.
00:43 Here we need to determine number of degrees of freedom which is n1 minus 1 that is 59.
00:55 And now let's use either calculator or a table to determine t.
01:00 Let's do this.
01:02 That is 2.
01:05 Now once it's calculated let's determine the confidence interval.
01:32 Then this confidence interval is from 86 .13 to 93 .87.
01:44 That is answer to question one.
01:47 Now let's move on to question two, question b...
