The results section of an article reports the following “IQ scores of the sample differ from the population mean of 100, single sample t (19) = 2.80, p < .05, two tail”. Based on this result, how many people were included in the sample? Select one: 20 21 19 38
Suppose are running a study/poll about the proportion of women over 40 who regularly have mammograms. You randomly sample 138 people and find that 91 of them match the condition you are testing.Suppose you are have the following null and alternative hypotheses for a test you are running:H0:p=0.67Ha:p>0.67Calculate the test statistic, rounded to 3 decimal places z=
What is the appropriate conclusion for this test? (Do not reject OR reject) H₀ and conclude that there (is or is not) sufficient evidence that mice with an average life span of 32 months will live to be (less or greater) than 42 months old when 40% of the calories in their diet are replaced by vitamins and protein.
An advertising firm has decided to ask 115 customers at each of four local shopping malls if they are willing to take part in a market research survey. At . = 0.05 is there evidence to show that the proportions are not all the same. A B D Willing 62 67 69 70 Not Willing 53 48 46 45 What are the expected numbers? (round to 3 decimal places) D Willing Not Willing The hypotheses are Ho : PA = pPB = Pc = Pp HA: At least one of the proportions is different. (claim) Since a = 0.05 the critical value is 7.815 The test value is: (round to 3 decimal places) The p-value is (round to 3 decimal places) So the decision is to do not reject Họ reject H, Thus the final conclusion is There is enough evidence to reject the claim that at least one of the proportions is different. There is enough evidence to support the claim that at least one of the proportions is different. There is not enough evidence to support the claim that at least one of the proportions is different. OThere is not enough evidence…
Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 595 randomly selected adults showed that 62% of them would erase all of their personal information online if they could. Find the value of the test statistic. The value of the test statistic is (Round to two decimal places as needed.)
Students in an elementary school both boys and girls were asked if they are willing to write a letter to their mother on Mother's Day as an assignment. Out of the 30 boys, only 9 answered "yes" while out of the 45 girls, 39 said that they are willing to write to their mother on Mother's Day. At 99% level of confidence, is there enough evidence to say that the proportion who said "yes" is more for girls than boys? .
