Answer:
Given,
Proportion p^c = (n1p1^ + n2p2^)/(n1 + n2)
substitute values
= (32*0.33 + 26*0.45)/(32+26)
= 22.26/58
= 0.383793103
= 0.384
Option E is right answer.
When performing a hypothesis test on the difference between 2 population proportions, the 2-test statistic equation...
How do you know if a hypothesis test is testing the claim between 2 population proportions or 2 means? How is the test statistic for a claim about 2 population means, independent samples, standard deviations unknown, similar to the test statistic for 1 population mean, standard deviation unknown? If the difference between the 2 population means is not significant, which means the test statistic falls within the "usual" area of the distribution, what is the decision about the null hypothesis?...
When testing the difference between two population proportions using large independent random samples, the __________ test statistic is used. z F t None of the other choices is correct. chi-square

When performing a hypothesis test for the ratio of two population variances, the upper critical F value is denoted FR. The lower critical F value, FL, can be found as follows: interchange the degrees of freedom, and then take the reciprocal of the resulting F value found in table A-5. FR can be denoted Fα/2 and FL can be denoted F1-α/2 . Find the critical values FL and FR for a two-tailed hypothesis test based on the following values: n1...

Answer this Based on these data, can the company conclude, at the 0.05 level of question by performing a hypothesstest regarding (which is μ with a letter d subscript), the population mean difference in assembly times for the two processes. Assume that this...
11. Construct the indicated confidence interval for the difference between population proportions. Assume that the samples are independent and that they have been randomly selected. A marketing survey involves product recognition in New York and California. Of 558 New Yorkers surveyed, 193 knew the product while 196 out of 614 Californians knew the product. Construct a 99% confidence interval for the difference between the two population proportions. 12. Construct the indicated confidence interval for the difference between population proportions. Assume...
Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2031 passenger cars in a particular region, 227 had only rear license plates. Among 300 commercial trucks, 45 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars....
statistics help 7) Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test ie, describe the values of the test statistic that would result in rejection of the null hypothesis Suppose you wish to test the claim that the mean value of the differences d for a population of paired data, is greater than 0. Given a sample of n-15 and a significance level of a-001, what criterion would be used for rejecting the null hypothesis...
