A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n=198, z=5.53, s=1.97. Use a 0.10 significancelevel to test the claim that the population mean of such ratings is less than 6.0O. Assume that a simple random sample has been selected. Identify the null and alternativehypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.The Hypotheses TestНо: д — 6.00H1: [ Select]Choose one of these A: u > 6.00B: µ < 6.00C: µ + 6.00Test statistic [ Select](А) t 3D — 3.36; (В) z —D —3.36Choose one of theseP value [ Select ]v < s.f. = 0.10[ Select ]" ( reject or do not reject)

At test for a mean uses a sample of 25 observations. Find the t test statistic value that has a P-value of 0.10 when the alternative hypothesis is (a) H: μ#0, (b) H₂:μ>0, (c) H₂: μ<0. (a) Find the t test statistic value when H₂: μ‡0. (Round to three decimal places as needed.) ***
Only 19% of registered voters voted in the last election. Will voter participation increase for the upcoming election? Of the 339 randomly selected registered voters surveyed, 75 of them will vote in the upcoming election. What can be concluded at the αα = 0.05 level of significance? The p-value = (Please show your answer to 4 decimal places.) The p-value is ? ≤ > αα Based on this, we should Select an answer reject accept fail to reject the null hypothesis. Thus, the final conclusion is that ... A) The data suggest the population proportion is not significantly higher than 19% at αα = 0.05, so there is statistically insignificant evidence to conclude that the percentage of registered voters who will vote in the upcoming election will be higher than 19%. B) The data suggest the population proportion is not significantly higher than 19% at αα = 0.05, so there is statistically significant evidence to conclude that the percentage of registered voters who will vote in the…
