The sample correlation coefficient between X and Y is 0.375. It hasbeen found out that the p-value is 0.256 when testing Ho :p = 0against the two-sided alternative H1:p not equal to 0. To test Ho :p =O against the one-sided alternative H1: p > 0 at a significance level of0.193, the p-value isO 0.256 /2O (0.256) 2O 1-0.256O 1-0.256 / 2

Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x = 101.16, y = 102.3, r= 0.810, P-value = 0.000, and y = 23.09+0.78x, where x represents the IQ score of the wife. Find the best %3D %3D %3D predicted value of y given that the wife has an IQ of 109? Use a significance level of 0.05.

Critical values: r = ±0.487, no significant linear correlation OD. Critical values: r = ±0.396, significant linear correlation
An agriculturist claims that she has cultivated a new variety of orange that has a significantly higher content of vitamin C than the variety that is currently the top seller. A random sample of 15 oranges of the new variety and a random sample of 13 oranges of the current top seller were sampled, giving the following results: n1 = 15 s? = 6.4460 n2 = 13 s3 = 9.0336 %3D 3.1 Test for the equality versus inequality of population variances using a significance level of 10%. Remember to include a picture of the rejection region showing both critical values (for the purpose of finding both critical values you will have to make use of Excel). 3.2 Which hypothesis test would be appropriate to determine whether the new variety of orange has a significantly higher content of vitamin C than the variety that is currently the top seller? Do NOT perform a hypothesis test – simply tell me which test should be used, why you chose this test, and give the formula for the test statistic.
Suppose data is obtained from 20 pairs of (x, y) and the sample correlation coefficient is 0.82. (a) Test the hypothesis that Ho: p = 0 against H1 :p + 0 with a = 0.05. (b) Test the hypothesis that Ho: p = 0.22 against H:p + 0.22 with a = 0.05. (c) Construct a 95% two-sided confidence interval for the correlation coefficient. Round your answer to 3 decimal places. i i Statistical Tables and Charts
Two samples were drawn independently from two normal populations. Sample 1: 11.6, 11.35, 10.1, 10.85, 10.35, 10.6, and 11.1.Sample 2: 5.85, 8.85, 9.85, 11.85 and 7.85.Test to determine whether the means of the two population differs (use α=0.05).
A Chi square test has been conducted to assess the relationship between marital status and church attendance. The obtained Chi square is 7.45 and the critical Chi square is 9.488. What may be concluded? Group of answer choices A.reject the null hypothesis, church attendance and marital status are independent B.fail to reject the null hypothesis, church attendance and marital status are independent C.Reject the null hypothesis, church attendance and marital status are dependent D.fail to reject the null hypothesis, church attendance and marital status are dependent
Do adults (age 20–45) with children and adults without children have the same distribution of type of vehicle that is driven? In a large city, 130 randomly selected adults with children and 170 randomly selected adults without children were asked which type of car best describes the vehicle they primarily drive: car, truck, van, or SUV. A significance test will be conducted using the data to determine if there is convincing evidence at α = 0.05 that the distribution of type of vehicle driven differs between adults (age 20–45) with children and adults without children. What are the hypotheses for this test? H0: There is in the distribution of vehicle type driven between adults (aged 20–45) with children and adults without children. Ha: There is in the distribution of vehicle type driven between adults (aged 20–45) with children and adults without children.
A researcher randomly assigns college freshmen to either of two experimental conditions. Because both groups consist of college freshmen, someone claims that it is appropriate to use a t test for the two related samples. Comments?
