- Answer all these questions A, B and C questions.arrow_forwardyou 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 _____ .arrow_forwardThe P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a= 0.01, (b) a = 0.05, and (c) α=0.10. P=0.1123 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? ve this OA. Fail to reject Ho because the P-value, 0.1123, is less than α = 0.01 OB. Reject Ho because the P-value, 0.1123, is less than α=0.01. OC. Fail to reject Ho because the P-value, 0.1123, is greater than α=0.01.

The claim is that for 12 AM body temperatures, the mean is μ>98.6°F. The sample size is n=9 and the test statistic is t=2.262.arrow_forwardUse technology to find the P-value for the hypothesis test described below. The claim is that for 12 AM body temperatures, the mean is mu greater than 98.6 degrees F. The sample size is n equals 8 and the test statistic is t equals 1.349. P-value equals (Round to three decimal places as needed.)arrow_forward
- hii! can someone help with this? thank you!!arrow_forwardSolve the problem. A researcher conducts a hypothesis test on a population proportion. Her null and alternative hypothesis are Ho: p = 0.6 and Ha: P < 0.6. The test statistic and p-value for the test are z = -1.51 and p-value = 0.0655. For a significance level of a = 0.05, choose the correct conclusion regarding the null hypothesis. O None of these. O There is sufficient evidence to warrant rejection of the null hypothesis. There is insufficient evidence to warrant rejection of the null hypothesis. STEP 1/3 Routin We're findi answer you In the mea DIVE DEEParrow_forwardfill in the blankarrow_forward
- Test the claim that the proportion of people who own cats is significantly different than 80% at the 0.1 significance level. The alternative hypothesis would be: p 0.8 u > 0.8 µ < 0.8 p # 0.8 µ # 0.8 o The test is: left-tailed two-tailed right-tailed Based on a sample of 500 people, 75% owned cats The test statistic is: (to 2 decimals) The p-value is: (to 2 decimals)arrow_forwardUse 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 is n = 3 and the test statistic is t = 1.234.arrow_forwardImagine you are doing a Related-Samples t-test, and you are on Step Four of the hypothesis test. The study you are doing is testing whether there’s a significant difference between the anxiety of people before and after a final exam. The APA sentence is t(28) = 3.45, p < .05, d = 1.05. What is the correct set of conclusions that goes with this APA sentence? Group of answer choices Reject the H0, conclude that there IS a difference in anxiety, conclude based on effect size that the difference is small. Fail to Reject the H0, conclude that there IS a difference in anxiety. Reject the H0, conclude that there IS NOT a difference in anxiety, conclude based on effect size that the difference is small. Fail to Reject the H0, conclude that there IS NOT a difference in anxiety. Reject the H0, conclude that there IS a difference in anxiety, conclude based on effect size that the difference is large.arrow_forward
