A hypothesis test is conducted with H0:μ=46 and H1:μ≠46 A simple random sample of size n=68n=68 is drawn, with x¯=52, and s=15.   Determine the P-value. (Round to four decimals places.)

A company wants to determine whether it's consumer product ratings (0-10) have changed from last year to this year. The table below shows the company's product ratings from 8 consumers for last year and this year. At a=0.05, is there enough evidence to conclude that the ratings have changed? Assume the samples are random and dependent, and the population is normally distributed. Complete parts A-F.

Conduct a test at the α=0.01 level of significance by determining ​(a) the null and alternative​ hypotheses, ​(b) the test​ statistic, and​ (c) the​ P-value. Assume the samples were obtained independently from a large population using simple random sampling.   Test whether p1>p2. The sample data are x1=124​, n1=243​, x2=139​, and n2=312.

Many college and university students obtain summer jobs. A professor wanted to determine whether students in different degree programs earn different amounts. She randomly selected five students in each of the 4 university programs and asked them to report what they earned the previous summer (in thousands of dollars). The following partially filled-in ANOVA table was obtained. Fill-in the rest of the table. (Use exact values for df and round all other numbers to 2 decimal places, if needed.) Source df SS MS F-Stat Treatments   11.0     Error         Total   23.7

Let x be a random variable that represents blood glucose level after a 12-hour fast. Let y be a random variable representing blood glucose level 1 hour after drinking sugar water (after the 12-hour fast). Units are in milligrams per 10 milliliters (mg/10 ml). A random sample of eight adults gave the following information. Σχ - 64.2; Σ ? = 528.24; Ey = 90.4; Ey² = 1063.88; Exy = 741.77 6.2 8.6 7.0 7.5 8.3 6.9 10.0 9.7 y 9.7 10.3 10.9 11.5 14.2 7.0 14.6 12.2 Find the equation of the least-squares line. (Round your answers to three decimal places.) Find the sample correlation coefficient r and the sample coefficient of determination r. (Round your answers to three decimal places.) r = 2 = If x = 7.0, use the least-squares line to predict y. (Round your answer to two decimal places.) y = Find an 80% confidence interval for your prediction.

A study was done on the body temperatures of men and women. The results are shown in the table. 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) below. Use a 0.010.01significance level for both parts.     Men      Women μ μ1 μ2 n 11 59 x overbar 97.67°F 97.22°F s 0.77°F 0.66°F   Test the claim that men have a higher mean body temperature than women.   What are the null and alternative​ hypotheses?   The test​ statistic, t, is __________ The​ P-value is __________   State the conclusion for the test.   Construct a confidence interval suitable for testing the claim that men have a higher mean body temperature than women. __________ <μ1 − μ2 < __________   Does the confidence interval support the conclusion found with the hypothesis​ test? __________, because the…

Answer P1 please! Both parts of the question!

10:49 Claim: Most adults would erase all of their personal information online if they could. A software fiem survey of 632 randomly selected adults showed that 62% of them would erase all of their personal information online if they could. Find the value of the test statistic. The value of the test statistic is (Round to two decimal places as needed.)

Conduct a test at the a = 0.01 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume the samples were obtained independently from a large population using simple random sampling. Test whether p, > P2. The sample data are x, =118, n, = 258, x, = 139, and n, = 314.
