11. A recipe submitted to a magazine by one of its subscribers states that the mean baking time for acheesecake is 55 minutes. A test kitchen preparing the recipe before it is published in themagazine makes the cheesecake 10 times at different times of the day in different ovens. Thefollowing baking times (in minutes) are observed.54 55 58 59 5960 61 61 62 65Assume that the baking times belong to a normal population. Test the null hypothesis that the meanaking time is 55 minutes against the alternative hypothesis u> 55. Use a= .05.

14. Sports Car: Fuel Injection The manufacturer of a sports car claims that the fuel injection system lasts 48 months before it needs to be replaced. A consumer group tests this claim by surveying a random sample of 10 owners who had the fuel injection system replaced. The ages of the cars at the time of replacement were (in months): LEGO 29 42 49 48 53 46 30 51 42 52 (i) Use your calculator to verify that the mean age of a car when the fuel injection system fails is x = 44.2 months, with standard deviation S=8.61months. (ii) Test the claim that the fuel injection system lasts less than an average of 48 months before needing replacement. Use a 5% level of significance. %3D
An experiment was conducted to determine whether giving candy to dining parties resulted in greater tips. The mean tip percentages and standard deviations are given in the accompanying table along with the sample sizes. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b). OA. Ho: H₁ H₂ H₁: H₁ H₂ OC. Ho: H₁ H₁: H₁ C a. Use a 0.05 significance level to test the claim that giving candy does result in greater tips.

A graduate student is interested in how viewing different types of scenes affects working memory. For his study, he selects a random sample of 36 adults. The subjects complete a series of working memory tests before and after walking in an urban setting. Before the walk, the mean score on the test of working memory was 9.1. After the walk, the mean score was 1.4 higher. The graduate student has no presupposed assumptions about how viewing different types of scenes affects working memory, so he formulates the null and alternative hypotheses as: H00 : μDD = 0 H11 : μDD ≠ 0 Assume that the data satisfy all of the required assumptions for a repeated-measures t test. The graduate student calculates the following statistics for his hypothesis test: Mean difference (MDD) 1.4 Estimated population standard deviation of the differences (s) 1.6 Estimated standard error of the mean differences (sMDMD) 0.2667 Degrees of freedom (df) 35 The t statistic 5.25 The critical values of t…
A survey of 25 randomly selected customers found the ages shown (in years). The mean is 32.92 years and the standard deviation is 10.19 years. a) What is the standard error of the mean? b) How would the standard error change if the sample size had been 400 instead of 25? (Assume that the sample standard deviation didn't change.) 22 21 35 23 33 35 26 44 44 14 48 25 27 12 43 48 38 46 36 35 38 38 32 23 37 ... a) The standard error of the mean is (Round to two decimal places as needed.) b) How would the standard error change if the sample size was 400 instead of 25 with the same sample standard deviation? Select the correct choice below and fill in any answer boxes within your choice. O A. The standard error would increase. The new standard error would be times the old. B. The standard error would decrease. The new standard error would be the old standard error divided by O C. The standard error would not change.
A tax collector wishes to see if the mean values of the tax-exempt properties are different for two cities. The values of the tax-exempt properties for the two random samples are show. The data are given in millions of dollars. At the 0.05 level of significance, is there enough evidence to support the tax collector's claim that the means are different?

What is the point estimate for the average wait time for callers? b. Verify conditions for using this sample to predict population mean of wait times. Estimate the mean wait time for all callers to this restaurant, with 90% confidence. Write your answer as a sentence. C. d. Estimate the standard deviation of wait times for all callers to this restaurant, with 90% confidence. Write your answer as a sentence. (You do not need to check requirements.)
A standardized test for graduate school admission has a mean score of 159 with a standard deviation of 8 and a unimodal, symmetric distribution of scores. A test preparation organization teaches small classes of 4 students at a time. A larger organization teaches classes of 64 at a time. Both organizations publish the mean scores of all their classes. A mean score of 167 is SD _____ above the mean for the smaller organization, and ______ SD above the mean for the larger organization. It is more likely that the smaller organization will have that success.
