Listed below are amounts of court income and salaries paid to the town justices for a certain town. All amounts are in thousands of dollars. Find the​ indicated prediction interval. There is sufficient evidence to support a claim of a linear​ correlation, so it is reasonable to use the regression equation when making predictions. For the prediction​ interval, use a 99​% confidence level with a court income of ​$800​,000.   Court_Income    Justice_Salary64                        29412                     491553                   901144                   51272                     47252                     61102                     20157                     3026                       22   Lower Bound[LB] < y < Upper Bound[UB] - Approximate upto 2 decimal places  

Conduct the hypothesis test and provide the test statistic and the critical​ value, and state the conclusion. A person purchased a slot machine and tested it by playing it 1,117 times. There are 10 different categories of​ outcomes, including no​ win, win​ jackpot, win with three​ bells, and so on. When testing the claim that the observed outcomes agree with the expected​ frequencies, the author obtained a test statistic ofχ2=11.516. Use a 0.025 significance level to test the claim that the actual outcomes agree with the expected frequencies. Does the slot machine appear to be functioning as​ expected?

Listed below are the numbers of deaths resulting from motor vehicle crashes. Let x represent the​ year, with 1975 coded as x=​1, 1980 coded as x=​6, 1985 coded as x=​11, and so on. Construct a scatterplot and identify the mathematical model that best fits the given data. Use the best model to find the projected number of deaths for the year 2030. x_(year)    y_(deaths)1975    445141980    510681985    438221990    446061995    418202000    419292005    434652010    32717 Write the nonlinear equation.[Equation] Find the projected death.[ProjectedDeathin2030]  

An investigator analyzed the leading digits from 762 checks issued by seven suspect companies. The frequencies were found to be 224​, 129​, 80​, 67​, 75​, 57​, 46​, 36​, and 48​, and those digits correspond to the leading digits of​ 1, 2,​ 3, 4,​ 5, 6,​ 7, 8, and​ 9, respectively. If the observed frequencies are substantially different from the frequencies expected with​ Benford’s law shown​ below, the check amounts appear to result from fraud. Use a 0.01significance level to test for​ goodness-of-fit with​ Benford’s law.  Leading_Digit    Actual_Frequency    Benford’s_Law:1                              224                           30.10%2                             129                            17.60%3                               80                            12.50%4                               67                              9.70%5                               75                              7.90%6                               57                              6.70%7                               46                              5.80%8                               36                              5.10%9                               48                              4.60% Write upto 3 decimal points Find the test statistic[TestStatistic] Find the P-Value[Pvalue]

A certain statistics instructor participates in triathlons. The accompanying table lists times​ (in minutes and​ seconds) he recorded while riding a bicycle for five laps through each mile of a​ 3-mile loop.
