A sample of 32 Airport Data Speeds has a sample mean = 3.72 Mbps with a sample standard deviation of $s$ = 5.60 Mbps. The wireless service claims that the mean airport data speed is less than 4.00 Mbps. Use the sample above with a 0.05 significance to test this claim. What is the claim written in symbolic form? ? $\mu$ = 4.00 ? $\mu$ $\neq$ 4.00 ? $\mu$ > 4.00 ? $\mu$ < 4.00 What is the null hypothesis? ? $H_0$ : $\mu$ = 4.00 ? $H_0$ : $\mu$ $\neq$ 4.00 ? $H_0$ : $\mu$ > 4.00 ? $H_0$ : $\mu$ < 4.00 What is the alternative hypothesis? ? $H_1$ : $\mu$ = 4.00 ? $H_1$ : $\mu$ $\neq$ 4.00 ? $H_1$ : $\mu$ > 4.00 ? $H_1$ : $\mu$ < 4.00 What is the value of the test statistic used for the test? (Round to 3 decimal places) What is the absolute value of the critical value used for the test? (Round to 3 decimal places) Which conclusion best fits the results of the test? Reject $H_0$. The claim is supported. ? Reject $H_0$. The claim is not supported. Fail to Reject $H_0$. The claim is supported. ? Fail to Reject $H_0$. The claim is not supported. Use STAT TABLES, if necessary.

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 = 16.00 Mbps. The sample size is n = 14 and the test statistic is t = -2.404. The P-value is nothing. (Round to three decimal places as needed.)

The display provided from technology available below results from using data for a smartphone carrier's data speeds at airports to test the claim that they are from a population having a mean less than 4.00 Mbps. Conduct the hypothesis test using these results. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. T-Test t= -0.161736 p= 0.436089 x= 3.87 sx= 5.683571 n=50 Identify the test statistic : Identify the p-value : state the final conclusion that addresses the original claim. So, we ....... the null hypothesis. There is ..... evidence to conclude that A smartphone carrier’s data speeds at airports are from a population having a mean less than 4.00 Mbps.

The display provided from technology available below results from using data for a smartphone carrier's data speeds at airports to test the claim that they are from a population having a mean less than 5.00 Mbps. Conduct the hypothesis test using these results. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. Click the icon to view the display from technology. What are the null and alternative hypotheses? A. H0: μ = 5.00 Mbps H1: μ > 5.00 Mbps B. H0: μ = 5.00 Mbps H1: μ ≠ 5.00 Mbps C. H0: μ = 5.00 Mbps H1: μ < 5.00 Mbps D. H0: μ < 5.00 Mbps H1: μ = 5.00 Mbps Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. H0. There is evidence to support the claim that the sample is from a population with a mean less than 5.00 Mbps.
