A null and alternative hypothesis are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Hot 6 = 4.1 Ha: 6 # 4.1 What type of test is being conducted in this problem? O A. Left-tailed test O B. Right-tailed test O C. Two-tailed testA golf analyst claims that the standard deviation of the 1B-hole scores for a golfer is at least 3.3 strokes. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is le-tailed, right-tailed, or two-tailed. Explain your reasoning. r ..... \\ \\.J State the null hypothesis in words and in symbols. Choose the correct answer below. 0 A. The null hypothesis expressed in words is. \"the standard deviation of the 18-hole scores for a golfer is not 3.3 strokes.\" The null hypothesis is expressed symbolically as, \"Ho: a $3.3." O B. The null hypothesis expressed in words is, \"the standard deviation of the 18-hole scores for a golfer is equal to 3.3 strokes." The null hypothesis is expressed symbolically as, \"Ho: 5: 3.3.' O c. The null hypothesis expressed in words is, \"the standard deviation of the 18-hole scores for a golfer is at least 3.3 strokes.\" The null hypothesis is expressed symbolically as, \"Hg: 523.3." 0 D. The null hypothesis expressed in words is, \"the standard deviation of the 18-hole scores for a golfer is at most 3.3 strokes.\" The null hypothesis is expressed symbolically as, \"H\": a $3.3." A null hypothesis is rejected with a level of significance of 0.05. Is it also rejected with a level of significance of 0.10? Explain. -. .. . Choose the correct answer below. O A. Yes, the claim would be rejected because the P-value would be greater than 0.10. O B. Yes, the claim would be rejected because the P-value would be less than 0.10. O C. No, the claim would not be rejected because the P-value would be less than 0.10. O D. No, the claim would not be rejected because the P-value would be greater than 0.10.Use the calculator displays to the right to make a decision to reject or fail to reject the null hypothesis at a significance Z-Test Z-Test level of a = 0.10.
