Question

PLEASE READ THE QUESTION PROPERLY. Expert did not answer properly first time asked. I need help on part B and multiple choice.

(B1) If it is really the case that 16% of all plates blister under these circumstances and a sample size 100 is used, how likely is it that the null hypothesis of part (a) will not be rejected by the 0.05 test? (Round your answer to four decimal places.)

(B2)If it is really the case that 16% of all plates blister under these circumstances and a sample size 200 is used, how likely is it that the null hypothesis of part (a) will not be rejected by the 0.05 test? (Round your answer to four decimal places.)

(b) If it is really the case that 16% of all plates blister under these circumstances and a sample size 100 is used, how likely is it that the null hypothesis of part (a) will not be rejected by the 0.05 test? (Round your answer to four decimal places.)

A manufacturer of nickel-hydrogen batteries randomly selects 100 nickel plates for test cells, cycles them a specified number of times, and determines that 14 of the plates have blistered. (a) Does this provide compelling evidence for concluding that more than 10% of all plates blister under such circumstances? State and test the appropriate hypotheses using a significance level of 0.05 Ho: p> 0.10 Hai p = 0.10 O Ho: p = 0.10 Ha: P0.10 O Ho: p = 0.10 Ha: p # 0.10 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) P-value 0913 State the conclusion in the problem context. z = 1.33 Reject the null hypothesis. There is sufficient evidence that more than 10% of plates blister under the experimental conditions. O Do not reject the null hypothesis. There is sufficient evidence that more than 10% of plates blister under the expert mental conditions. O Do not reject the null hypothesis. There is not sufficient evidence that more than 10% of lates blister under the experimental conditions. Reject the null hypothesis. There is not sufficient evidence that more than 10% of plates blister under the experimenta conditions.

Explanation / Answer

Solution

MCQ : Do not reject the null hypothesis. there is not sufficient evidence that more than 10% of plates blister under the exprimental conditions.

(b1) z =( 0.16-0.1)/((0.1)(0.9)/100)0.5 = 2

p value = 0.02275

not rejecting the null hypothesis = 1-0.02275 = 0.9773

(b2) z =( 0.16-0.1)/((0.1)(0.9)/200)0.5 = 2.8284

not rejecting = 0.9977
