5. Suppose we perform the hypothesis test H 8 0 versus H 8 0. We find...
We wish to test H0: = 0 versus Ha: > 0. If we calculate a test statistic of = 0.6, then my p-value will be closest to 0.003 0.300 0.600 0.950 When estimating , the proportion of voting age citizens who will vote for Candidate A, political researchers calculate the 90% confidence interval (0.67, 0.73). If we were to also test the hypotheses H0: = 0.666 versus Ha: 0.666 using a significance level of = 0.10, we would decide to accept H0. reject H0. not reject...
If n<30, we cannot perform a hypothesis test for Ho:p = 0.5. O True O False
Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Ho: p = 0.65 versus H : p<0.65 n= 150, x= 87, a = 0.01 Is npo (1-po) 2 10? Ο Νο Yes Use technology to find the P-value. P-value = (Round to three decimal places as needed.)
and with minitab please. 4. Consider the hypothesis test Ho: o? =ož vs. H: 0}<03. Suppose that the sample sizes are nl = 5 and n2 = 10, and that S -23.2 and 53-28. Test this hypothesis using 5% significance.
P1 To test the hypothesis Ho: p = 1/2 against H :p < 1/2, we take a random sample of Bernoulli trials, X,X,..., X.,, and use for our test statistic Y = ¿x, which has a binomial distribution b(n, p). Let the critical region be defined by C ={y:y sc}. Find the values of n and c so that (approximately) a = 0.05 and B = 0.10 when p = 1/4. 1=1
Test the hypothesis using the P-value approach Be sure to verify the requirements of the test Ho p=0.64 versus H, p<0.64 n=150, x=84 c = 0.1 Is npo (1-Po) 210? O No O Yes Use technology to find the P-value P value - (Round to three decimal places as needed) because the P value is that a
Suppose 0 is in the interval 90° <O< 180°. Find the sign of the following. cos (0 + 90°) Choose whether the sign of cos (0+ 90°) is positive or negative. Negative Positive
Suppose you perform the hypothesis test H: = 35 versus H: 35. The population variance, o. is known. The sample size is n = 39. Assume the significance level is 0.06. 1) Should you use ort to find the critical value? Ot Oz 2) Choose the correct critical region. Reject H, if :> Reject H, if : 2 % Reject H, if : > Reject H, if : 2 Reject H, if :< - Reject H, if S - Reject...
5. Suppose Y represents a single observation from the probability density function given by: Soyo-1, 0, 0<y<1 elsewhere Find the most powerful test with significance level a=0.05 to test: HO: 0=1 vs. Ha: 0=2.
1. Suppose a t-test of Ho = 0 versus H : 0 has a p-value= 0.068 (a) If 11.2, what is the p-value for a t-test of Ho : u = 0 versus Ha i > 0? Draw a picture to support your answer. (b) If 11.2, what is the p-value for a t-test of Ho Draw a picture to support your answer. 0 versus Ha u > 0?
