Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim.The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a true mean temperature, . of 48"F, ideal for a certain type of German piluner The owner of the hrewery does not agree wth therefrigerator manufacturer, and claims he can prove that the true mean temperature is incorrect. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusaon innontechnical terms.O There is sufficient evidence to support the claim that the mean temperature is different from 4S'F.There is sufficient evidence to support the claim that the mean temperature is equal to 45F.O There is not sufficient evidence to support the claim that the mean temperature is equal to 45'F.O There is not sufficient evidence to support the claim that the mean temperature is different from 48°F.

Test is that whether the true mean temperature is incorrect

Assume a normally distributed population with a mean = 90 and standarddeviation = 12. Be sure to sketch the curves, include formulas & round appropriately. If you select one person at random from this population (M = 90, SD = 12)and find his/her score on this variable to be 68 would you be surprised/consider this score extreme (yes/no)? Why/why not? Be sure to show your work when justifying the answer.
The data represent individual observations on bath concentration from a chemical process. The target value is 10 and the process standard deviation is given as o = 0.8. (a) Use k = 0.5 and h =5, built a tabular CUSUM to quickly detect a shift of about lo in the process mean. Based on the tabular CUSUM, please conclude whether the process has a mean shift using h=5. If the process has a mean shift, please indicate at which sample this mean shift started.
Please solve for p value ,determine weather to reject hypothesis and state the conclusion for enough evidence
K A company is developing a new high performance wax for cross country ski racing. In order to justify the price marketing wants, the wax needs to be very fast. Specifically, the mean time to finish their standard test course should be less than 55 seconds for a former Olympic champion. To test it, the champion will ski the course 8 times. The champion's times (selected at random) are 54.9, 63.7, 48.1, 53.9, 49.3, 47.4, 53.7, and 44.9 seconds to complete the test course. Should they market the wax? Assume the assumptions and conditions for appropriate hypothesis testing are met for the sample. Use 0.05 as the P-value cutoff level. Choose the correct null and alternative hypotheses below. Ο A.

You are testing that the mean speed of your cable Internet connection is 100 Megabits per second. State the null and alternative hypotheses.
Data from the National Association of Realtors indicates that mean price of a home in Denver,Colorado, in the first three months of 2018 was $255,300. We can write this as 255.3 with unitsof thousands of dollars for our calculations. A random sample of 60 homes sold in 2020 had amean price of 235 (thousand dollars). Assume the standard deviation s = 140 (thousand dollars).Can we conclude that the mean price in 2020 differs from the mean price in the first 3 months of2018?

Someone once dropped a 'mint imperial", a type of sweet, from the top of a multi-story car park and it landed on my grandmother's head. The average speed of a falling mint imperial is 4 m/s and the velocity is a Gaussian distribution with standard deviation 0.25 m/s. If a mint travelling faster than 5 m/s causes injury, what is the chance my grandmother was injured? In fact she was fine, but very annoyed.

SOLVE FOR CRITICAL VALUE Two suppliers manufacture a plastic gear used in a laser printer. The impact strength of these gears measures in foot-pounds is an important characteristic. A random sample of 10 gears from supplier 1 results in x1 = 290 and s1 = 12 while another random sample of 16 gears from the second supplier results in x2 = 321 and s2 = 22. Is there evidence to support the claim that supplier 2 provides gears with higher mean impact strength. Use a =0.04, and assume that both populations are normally distributed with equal variances.Level of significance = 0.04
Professor Ramos has a packing plant in a machine packs carton with jars. A sales person claims that the machine she is selling will pack faster to test the claim the times It takes each machine to pack 10 cartons are recorded in seconds and the results are shown below population one new machine n=10 Mean =42.3 s=0.685 Present machine n=10 mean=43.23 S =0.750.Do the data provide significant evidence to conclude that on the average the new machine packs faster perform the required hypothesis test in the 5% level of significance assume the population standard deviation's are equal but unknown show all your steps setting up your null and alternative hypothesis.
