During the 2015 season, the home team won 142 of the 263 National Football League games. Is this strong evidence of a home field advantage in professional football? Test an appropriate hypothesis and state your conclusion. Be sure the appropriate assumptions and conditions are satisfied before you proceed. Use α = 0.05. Determine the hypotheses for this test. (The proportion of home teams winning is denoted by p.) Ho: P = HA: P (Type # (...) cimals.) 14

you did not answer this  Let p be the true proportion of firms with a chief marketing officer currently on their top management team. To conduct the hypothesis test, the null and alternative hypotheses are formulated as: H₀: p̄ p̄ = 0.42'; Haa: p̄ p̄ ≠ 0.42   H₀: p ≥ 0.42; Haa: p < 0.42   H₀: p = 0.42; Haa: p ≠ 0.42   H₀: p ≤ 0.42; Haa: p > 0.42     If the null hypothesis is true, the sampling distribution of the sample proportion p̄ p̄ can be approximated by a _____   with a mean  ______   and a standard deviation of ____    .   The test statistic is _____   .

Teat the claim abouy the population mean, u, at the given level of significance, a, using the given sample statistics. Claim:u=50; a=0.05; o=3.11. Sample statistics: x=48.4, n=71. i) Identify the null and alternative hypothesis. (Do not forget to find the standardized test statistic and critical values) ii) Determine tge outcome and conclusion of the test.

A sample​ mean, sample​ size, and population standard deviation are provided below. Use the​ one-mean z-test to perform the required hypothesis test at the 1​% significance level.   x=34​, n=20​, σ=7​, H0​: μ=37​, Ha​: μ≠37   The test statistic is z=___________ ​(Round to two decimal places as​ needed.)   Identify the critical​ value(s). Select the correct choice below and fill in the answer box within your choice. (Round to two decimal places as​ needed.)   A. The critical values are ±zα/2=±_________ B. The critical value is zα=____________ C. The critical value is −zα=____________   ________________ (Do not reject, Reject) the null hypothesis. The data ____________ ( provide, do not provide) sufficient evidence to conclude that the mean is ______________ (not equal to 37, less than 37, equal to 37, greater than 37)

Use technology to find the P-value for the hypothesis test described below. The claim is that for a smartphone carrier's data speeds at airports, the mean is µ = 14.00 Mbps. The sample size is n= 20 and the test statistic is t= -2.174. P-value = (Round to three decimal places as needed.)

Use technology to find the P-value for the hypothesis test described below. The claim is that for 12 AM body temperatures, the mean is µ> 98.6°F. The sample size isn=9 and the test statistic is t=2.568. P-value = (Round to three decimal places as needed.)

Use technology to find the P-value for the hypothesis test described below. The claim is that for 12 AM body temperatures, the mean is u> 98.6°F. The sample size is n = 6 and the test statistic is t= 2.287. P-value = (Round to three decimal places as needed.)

State whether the standardized test statistic z indicates that you should reject the null hypothesis.   ​(a)z=2.374 ​(b)z=2.304 ​(c)z=−2.138 ​(d)z=2.544   z0=2.330 For z=2.374​, should you reject or fail to reject the null​ hypothesis?

Use technology to find the P-value for the hypothesis test described below. The claim is that for a smartphone carrier's data speeds at airports, the mean is u = 16.00 Mbps. The sample size is n = 19 and the test statistic is t= 1.798. P-value = (Round to three decimal places as needed.)

Suppose are running a study/poll about the proportion of men over 50 who regularly have their prostate examined.
