b. Does the above sample evidence enable us to reject the null hypothesis at ? = 0.10? Yes since the p-value is less than the significance level. No since the p-value is greater than the significance level. No since the p-value is less than the significance level. Yes since the p-value is greater than the significance level. c. Does the above sample evidence enable us to reject the null hypothesis at ? = 0.05? Yes since the p-value is less than the significance level. Yes since the p-value is greater than the significance level. No since the p-value is less than the significance level. No since the p-value is greater than the significance level. d. Interpret the results at ? = 0.05. We conclude that the population mean is less than 208. We cannot conclude that the population mean is less than 208. We conclude that the population proportion differs from 208. We conclude that the population proportion equals 208.

Unfortunately, you didn't provide the p-value or the sample statistics needed to calculate it. However, I will guide you on how to answer these questions once you have the p-value. Show moreā¦

Consider the following hypotheses: H0: Ī¼ ā„ 199 HA: Ī¼ < 199 A sample of 98 observations results in a sample mean of 195. The population standard deviation is known to be 32. Calculate the value of the test statistic. a-2. Find the p-value. 0.025 p-value < 0.05 0.05 p-value < 0.10 p-value greater than or equal to 0.10 p-value < 0.01 p-value < 0.025 b. Does the above sample evidence enable us to reject the null hypothesis at Ī± = 0.05? No since the p-value is greater than the significance level. Yes since the p-value is less than the significance level. Yes since the p-value is greater than the significance level No since the p-value is less than the significance level. c. Does the above sample evidence enable us to reject the null hypothesis at Ī± = 0.01? No since the p-value is greater than the significance level. No since the p-value is less than the significance level. Yes since the p-value is greater than the significance level. Yes since the p-value is less than the significance level. d. Interpret the results at Ī± = 0.01. We cannot conclude that the population mean is less than 199. We conclude that the population mean is less than 199. We conclude that the population proportion differs from 199. We conclude that the population proportion equals 199.

Consider the following hypotheses: H0: Ī¼ ā„ 205 HA: Ī¼ < 205 A sample of 83 observations results in a sample mean of 202. The population standard deviation is known to be 33. (You may find it useful to reference the appropriate table: z table or t table) a-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) a-2. Find the p-value. 0.025 p-value < 0.05 0.05 p-value < 0.10 p-value 0.10 p-value < 0.01 0.01 p-value < 0.025 b. Does the above sample evidence enable us to reject the null hypothesis at Ī± = 0.10? No since the p-value is greater than the significance level. Yes since the p-value is less than the significance level. Yes since the p-value is greater than the significance level. No since the p-value is less than the significance level. c. Does the above sample evidence enable us to reject the null hypothesis at Ī± = 0.05? No since the p-value is greater than the significance level. No since the p-value is less than the significance level. Yes since the p-value is greater than the significance level. Yes since the p-value is less than the significance level. d. Interpret the results at Ī± = 0.05. We cannot conclude that the population mean is less than 205. We conclude that the population mean is less than 205. We conclude that the population proportion differs from 205. We conclude that the population proportion equals 205.

b-2. Find the p-value. 0.025 ā¤ p-value < 0.05 0.01 ā¤ p-value < 0.025 p-value < 0.01 p-value ā„ 0.10 0.05 ā¤ p-value < 0.10 c. At the 10% significance level, what is the conclusion to the hypothesis test? Do not reject H0 since the p-value is greater than the significance level. Reject H0 since the p-value is less than the significance level. Do not reject H0 since the p-value is less than the significance level. Reject H0 since the p-value is greater than the significance level.
