A data set about speed dating includes "like" ratings of male dates made by the female dates. Thesummary statistics are n=198, =5.53, s=1.97. Use a 0.10 significance level to test the claim thatthe population mean of such ratings is less than 6.00. Assume that a simple random sample hasbeen selected. Identify the null and alternative hypotheses, test statistic, P-value, and state thefinal conclusion that addresses the original claim.The Hypotheses TestHo:µ = 6.00%3DH1: [Select][ SelectV Choose one of these A: u > 6.00Β : μ< 6.00C:H 7 6.00Test statistic [ Select ]v Choose one of these(A) t = – 3.36;-(B) z = -3.36P value [ Select ]< s.f. = 0.10[ Select ]( reject or donot reject)<>

Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x = 98.46, y = 99.4, r=0.883, P-value = 0.000, and y=-14.65 +1.16x, where x represents the IQ score of the wife. Find the best predicted value of y given that the wife has an IQ of 101? Use a significance level of 0.05. Click the icon to view the critical values of the Pearson correlation coefficient r. The best predicted value of y is (Round to two decimal places as needed.)

According to the Statistical Abstract of the United States, the mean family size in 2010 was 3.14 persons. Suppose a random sample of 225 families taken this year yields a sample mean size of 3.05 persons, and suppose we assume the population standard deviation of family sizes is o = 1 person. Using a 5% significance level, test the hypothesis that the mean family size has decreased since 2010. Perform your hypothesis test, and select the best interpretation of your results from the choices below. Select one: O a. At the 5% level of significance the data are statistically significant. We cannot determine the average family size has decreased since 2010. O b. At the 5% level of significance the data are statisticall significant. We can determine the average family size has decreased since 2010. O c. At the 5% level of significance the data is not statistically significant. We cannot conclude the average family size has decreased since 2010. O d. At the 5% level of significance the data…
