C) H1 : E(Y)≠μY0
the 2 sided alternate hypothesis claims that a parameter is not equal to value given by null hypothesis and it does not tell about the direction where as one sided hypothesis shows the rejection region is either on right or left side. so correct solution is c) H1:E(Y)≠μY0

Determine whether the following llustrate a one-sided altemative hypothesis or a two-sided alternative hypothesis. 1.Ho: EM- Y, 0 vs. H1: Em>>Y. 0. This example lustrates a 2. Ho: EM.,Y, o vs. Hti Em s #x 0, This example llustrates a 3, Ho: EM.,Y, vs. MpE(Y) * #x0. This example illustrates a altenative hypothesis alternative hypothesis. alternative hypothesis Y altermative hypothesis states the value is olther greater than or less than py o but not both, whereas a alternative hypothesis simply...
E) None of these Express the null hypothesis and the alternative hypothesis in symbolic form. The owner of aA football team claims that the average attendance at games is over 63,500, and he is therefore justified in moving the team to a city with a larger stadium.

The principal of SELECT ALL APPLICABLE CHOICES A) B) a middle school claims that test scores of the seventh-graders at her school vary less than the test scores of seventh-graders at a neighboring school, which have variation described by σ-14.7 Ho : σ〉14.7 Ho : σ < 14.7 H1: σ<14.7 H1 : σ> 14.7 C) D) Ho: σ>14.7 Ho: σ<14.7 H1 :...
49. The p-value for a two-sided hypothesis test of the null hypothesis Ho: μ = 12 is 0.07. Which of the following confidence intervals would include the value 12? 1. 90% Confidence Interval 2. 95% Confidence Interval 3. 99% Confidence Interval a. 1 and 2 b. 2 and 3 c. 1 only d. 1, 2, and 3 e. Impossible to Determine
The p-value for a two-sided hypothesis test is 0.04 for the null hypothesis Ho: μ = 15. Does the 95% confidence interval associated with the test include the value 15? YES, NO, OR UNABLE TO DETERMINE?

4. Exercise Let X, Y be RVs. Denote E[X] = Hy and E[Y] =py. Suppose we want to test the null hypothesis Ho : Mx = uy against the alternative hypothesis Hi : 4x > uy. Suppose we have i.i.d. pairs (X1,Yı),...,(Xn, Yn) from the joint distribution of (X,Y). Further assume that we know the X - Y follows a normal distribution. (i) Show that exactly) T:= (X-Y)-(ux-uy) - tn-1), Sin (3) where s2 = n-1 [?-,((X; – Y;) –...
For the following hypothesis test, determine the null and alternative hypotheses. Also, classify the hypothesis test as two tailed, left tailed, or right tailed The mean local monthly bill for cell phone users in this country was $43.56 in 2001. A hypothesis test is to be performed to determine whether last year's mean local monthly bill for cell phone users has decreased from the 2001 mean of $43.56 Choose the correct null and alternative hypotheses below OA. Ho : μ...
12. Consider a statistical inference that test the null hypothesis be Ho: c against H : esuch that c is a positive value. The test statistic associated with this mull hypothesis is given by t(b-c)/se(b) At significance level a, the test statistic is smaller than the critical value te(a/2, N - 2), that is iste(a/2, N- 2). Mark the correct alternative: (a) The test p-value increases if we increase c. (b) c does not belong to the estimated confidence interval...
