Testing: H0:μ=21.41H0:μ=21.41 H1:μ≠21.41H1:μ≠21.41 Your sample consists of 46 subjects, with a mean of 21.5 and standard deviation of 3.58. Calculate the test statistic, rounded to 2 decimal places. t=t= Suppose are running a study/poll about the proportion of men over 50 who regularly have their prostate examined. You randomly sample 136 people and find that 75 of them match the condition you are testing. Suppose you are have the following null and alternative hypotheses for a test you are running:...

The one-sample t statistic for testing H0: μ = 40 Ha: μ ≠ 40 from a sample of n = 13 observations has the value t = 2.77. (a) What are the degrees of freedom for t? (b) Locate the two critical values t* from the Table D that bracket t. < t < (c) Between what two values does the P-value of the test fall? 0.005 < P < 0.01 0.01 < P < 0.02 0.02 < P <...
A t statistic of 1.2 is computed from a large simple random sample of 10,000 observations to test a null hypothesis H0: μ-O, against an alternative Ha. The test is performed at a level of significance of 0.05. what is the corresponding p-value if the alternative is Ha: μ+0 ? (not equal to zero) Hint: For large samples, the t-statistic follows the N(O,1) distribution just as the z-statistic
