Ho: H1 H2 Ha: H1 SH2 Find the standardized test statistic t. t=O (Round to two decimal places as needed.) Find the P-value. P=D (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis and interpret the decision in the context of the original claim. V Ho. There enough evidence at the 5% level of significance to reject the claim.

Construct the confidence interval for the population mean u. c = 0.90, x = 5.3, o = 0.8, and n= 54 A 90% confidence interval for u is ( D. (Round to two decimal places as needed.) Enter your answer in the edit fields and then click Check Answer. All parts showing Type here to search

Choose the correct result of the hypothesis test for the P-value approach below. OA: Reject the null hypothesis, because the P-value is greater than α. OB. Reject the null hypothesis, because the P-value is less than α. OC. Do not reject the null hypothesis, because the P-value is greater than α. O D. Do not reject the null hypothesis, because the P-value is less than a. #3 80 F3 E $ 4 000 F4 R % 5 F5 T MacBook Air < 6 F6 Y & 7 AA F7 U * 0 8 DII F8 ( 9 DD F9 C I 0

Scenario: 200 people were asked, “Who is your favorite superhero?” Below are the data.  Test the null hypothesis that the population frequencies for each category are equal.  α= .05. Iron Man Black Panther Wonder Woman Spiderman fo = 40 fo = 60 fo =55 fo = 45 fe = fe = fe = fe =   Chi Square test statistic = ______ Group of answer choices

The null hypothesis and the alternate hypothesis are: H: The frequencies are equal. H₁: The frequencies are not equal. Category fe ABC D 15 10 10 15 a. State the decision rule, using the 0.05 significance level. (Round your answer to 3 decimal places.) Reject Ho if chi-square > b. Compute the value of chi-square.
