A researcher claims that 90% of people trust DNA testing. In a survey of 100 people, 91 of them said that they trusted DNA testing. Is the actual proportion of people who trust DNA testing larger than 90%? Test the researcher’s claim at the 1% level of significance. (Null and Alternate Hypothesis, Rejection Region) A. Ho: p = 0.90; Ha: p < 0.90; Rejection Region: z < -2.576 B. Ho: p = 0.90; Ha: p < 0.90; Rejection Region: z < -2.326 C. Ho: p = 0.90; Ha: p > 0.90; Rejection Region: z > 2.326 D. Ho: p = 0.90; Ha: p > 0.90; Rejection Region: z > 1.960 E. Ho: p = 0.90; Ha: p ≠ 0.90; Rejection Region: z < -2.576 or z > 2.576 (Test Statistic and conclusion) A. z = 0.333; FRHo (No sufficient evidence to reject the claim) B. z = 0.351; RHo (Sufficient evidence exists to reject the claim) C. z = 0.333; RHo (Sufficient evidence exists to reject the claim) D. z = 0.351; FRHo (No sufficient evidence to reject the claim) E. z = 0.00033; RHo (Sufficient evidence exists to reject the claim)

E. Ho: p = 0.90; Ha: p ≠ 0.90; Rejection Region: z < -2.576 or z > 2.576
(Test Statistic and conclusion)
A. z = 0.333; FRHo (No sufficient evidence to reject the claim)
B. z = 0.351; RHo (Sufficient evidence exists to reject the claim)
C. z = 0.333; RHo (Sufficient evidence exists to reject the claim)
