The cost of a daily newspaper varies from city to city. However, the variation among prices remains steady with a standard deviation of $0.20. A study was done to test the claim that the mean cost of a daily newspaper is $1.00. Thirteen costs yield a mean cost of $0.97 with a standard deviation of $0.18. Do the data support the claim at the 1% level? Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, however.) Part (a) State the null hypothesis. O Ho: M p-value, we reject the null hypothesis. Since a > p-value, we do not reject the null hypothesis. Since a 4.5 O Ha:,44.5 El Part (c) In words, state what your random variable )7 represents. 0 )7 represents the average length of time it takes students to nish their undergraduate degrees. 0 )7 represents the average number of students who receive an undergraduate degree in California. O )7 represents the average number of students in the California university system. O )7 represents the length of time it takes a student to nish his or her undergraduate degree. El Part (d) State the distribution to use for the test. (Enter your answer in the form 2 or tdfwhere df is the degrees of freedom.) E El Part (9) What is the test statistic? (If using the 2 distribution round your answers to two decimal places, and if using the tdistribution round your answers to three decimal places.) -Select- V = El Part (i) What is the pvalue? (Round your answer to four decimal places.) :1 Explain what the p-value means for this problem. 0 If H0 is true, then there is a chance equal to the p-value that the average time needed to complete an undergraduate degree is 5.1 years or more. 0 If H0 is false, then there is a chance equal to the p-value the average time needed to complete an undergraduate degree is not 5.1 years or more. 0 If H0 is false, then there is a chance equal to the p-value that the average time needed to complete an undergraduate degree is 5.1 years or more. 0 If H0 is true, then there is a chance equal to the p-value the average time needed to complete an undergraduate degree is not 5.1 years or more. Sketch a picture of this situation. Label and scale the horizontal axis and shade the region(s) corresponding to the pvalue. l/2(pvalue) Part (h) Indicate the correct decision ("reject" or "do not reject" the null hypothesis), the reason for it, and write an appropriate conclusion. (i) Alpha (Enter an exact number as an integer, fraction, or decimal.) a = (ii) Decision: O reject the null hypothesis O do not reject the null hypothesis (iii) Reason for decision: O Since a > p-value, we reject the null hypothesis. O Since a > p-value, we do not reject the null hypothesis. O Since a
