Question

Suppose that we are to conduct the following hypothesis test: Ho : u = 1020 H: 1 # 1020 Suppose that you also know that o = 230. n = 90. x = 1056.8, and take a = 0.05. Draw the sampling distribution, and use it to determine each of the following: The value of the standardized test statistic (test data z data or t data): Type your answer here Note: For the next part, your answer should use interval notation. An answer of the form (-00, a) is expressed (-infty, a), an answer of the form (b, ) is expressed (b, infty), and an answer of the form (-0, a) u (b, o) is expressed (-infty, a) u (b, infty).The rejection region for the standardized test statistic: ( Type your answer here Type your answer here Jul Type your answer here Type your answer here ) The p-value is the area of the rejection region. What is the p value? Type your answer here Your decision for the hypothesis test will be on the paper.

Answer 1

sole (a) value of standartasks test statistic Z= X -u olin 1056.8-10 DO 230 1190 1.52 (6) The rejection region for the standardused test statistis Za = 2005/2 Zo.225 - 11.96 (-0, - 1.96) u - 1.96) u ( 1.96, ( م (c) P-value P(Z = 1.52) 0.1285 cd ) Deuston Do not reject Ho. Since P-value is greater than q=0.05. The result is not significant CS Scanned with CamScanner
