For each of the questions below, test the hypotheses using the critical value method and the p-value method. Several retired bicycle racers are coaching a large group of young prospects. They randomly select seven of their riders to take part in a test of the effectiveness of a new dietary supplement that is supposed to increase strength and stamina. Each of the seven riders does a time trial on the same course. Then they all take the dietary supplement for 4 weeks. All other aspects of their training program remain as they were prior to the time trial. At the end of the 4 weeks, these riders do another time trial on the same course. Test at the 2.5% significance level whether taking this dietary supplement results in faster times in the time trials. Use a test statistic (₂) of 1.983.

Please show work in excel Stars Co. wants to advertise its products in the hope that more advertising will result in more sales. The following data have been collected in the past year showing money spent on advertising in a month and sales on the same month: a) Develop a regression equation to forecast the Sales as a function of the Advertising by drawing a scatter chart in Excel. b) Suppose that the company would like to advertise in the amount of 30 thousands. Estimate the Sales in response to this amount of advertising.

I need the answer as soon as possible
I recently asked this question and was wondering if you could show me how to do it, not just putting it in a caculator or excel but written out equations and seeing my information plugged in so I can understand. Thank you. Calculate the simple linear regression to determine if the amount of time spent on homework can be predicted by amount of sleep. Graph the relationship and determine, numerically, if there are any outliers. Interpret all results in a paragraph citing the appropriate statisitcs.
Two teams (A and B) are trying to improve AirTag quality by increasing the maximum Bluetoothrange of the AirTag. Your supervisor asked you to compare the two different prototypes by the teams. You need to examine 50 AirTag samples from each team (i.e., total of 100 AirTags from both teams) and measure their maximum Bluetooth range. Use the maximum Bluetooth range results for the prototypes designed by team A and team B shown in table 1 below to determine the following: (1-a) What is the mean, mode, median, and standard deviation of the maximum Bluetooth range for each team of AirTag? Show all work. (1-b) Divide each data group into five categories and create the frequency table. (1-c) Calculate the mean and standard deviation from the frequency tables and compare them to the results found in part (1-a). (1-d) Present the data as a histogram. (1-e) Present the data as a frequency polygon Note : last two numper = 20
A case-control study is being planned to see whether proximity to a nuclear power plant is associated with the development of certain cancers. 200 cases and 200 controls will be recruited and the distance from the nearest nuclear power plant will be dichotomized as close (< 3 miles) or far (≥ 3 miles). Use SAS to complete each problem below. (d) Since investigators find it very difficult to recruit cases, they decide to recruit three times as many controls as cases. How many cases and controls will they need to recruit in order to have 80% power? (Still assume a 2-sided, 5% level test, the same exposure probability among controls, and same OR.) If everything stays the same as above but the level of the test is reduced below 5%, what would happen to the total sample size computed first? (e) It is believed that about 4% of controls live close to the plant and the OR that investigators would be interested in detecting is 3.5. Assuming that a 2-sided, 5% level test will be…
A student is preparing to take a stand allies exam she was told that she needs to get plenty of sleep the night before the exam she is interested in the relationship between the number of hours of sleep a student gets her for an exam and the score earned on the exam. She collects information from 10 other students who have already taken the exam as shown on the table. she fits at least squares regression line to the data and determines the equation of the line is why equals 26-0.18 X where why is the score earn on the exam and ask is the number of hours of sleep the night before the exam. The residual is given. based on the residual plot is the linear model appropriate? no, there is no clear pattern in the residual plot. yes, there is no clear pattern in the residual plot. no, the student who got the most you've had a negative residual yes, there are more negative residuals (6) then positive residuals (4)
