Question: assume that a simple random sample has been selected from...

Question details

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. State the final conclusion that addresses the original claim and select three correct choices. A machine dispenses a liquid drug into bottles in such a way that the standard deviation of the contents is 81 milliliters. A new machine is tested on a sample of 24 containers and the standard deviation for this sample group is found to be 26 milliliters. At the 0.05 level of significance, test the claim that the amounts dispensed by the new machine have a smaller standard deviation. SELECT ALL APPLICABLE CHOICES A) There is enough evidence to support the Claim B) H1 : σ<81 (claim) Ho: σ 81 C) There is enough evidence to reject the Ho D) There is NOT enough evidence to support the Claim E) (claim) H1 : Ho : F There is NOT enough evidence to reject the Ho G) None of these σ<26 σ>26An article in a journal reports that 34 percent of American fathers take no responsibility forAThre is enough evidence to support the Claim child care. A researcher claims that the figure is higher for fathers in the town of Littleton. A C) random sample of 234 fathers from Littleton yielded 96 who did not help with child care. Test the researchers claim at the 0.05 significance level. (there are three correct choices in this question) SELECT ALL APPLICABLE CHOICES A) T B) Not enough evidence to reject the Claim D) Ho: p234 Ho: p34 Hi p<.34 (claim) Hi p> 34 (claim) E) There is enough evidence to reject the Ho F) There is enough evidence to reject the Claim G) Not enough evidence to reject the Ho H) There is enough evidence to support the Ho I) None of these
