Answer:
Part 2 of 3:
Since the true value, mu=38, which means we fail to reject null hypothesis, results in type2 error
Therefore, the result is a type2 error
A. SOLUTION:- Given data, ?0:? = 17 ?1:? < 17 ? = 0.05 ? = −1.62. From z table p value is 0.0526 What is your decision:- P>? So, we can fail to reject ?0 Using your answer from part a, If the true value of ? is 17, is the result a Type I error, a Type II error or a correct decision? Using your answer from part a, If the true value of ? is 10, is the...
please explain how you determine which error it is as well
A test of Ho: μ-51 versus HI : μメ51 is performed using a significance level of α-0.01. The value of the test statistic is z 2.34. Part 1 of 3 Determine whether to reject Ho Y in the critical region, we ireject Since the test statistics 1 Ho at the α-0.01 level. Part 2 of 3 If the true value of u is 51, is the result a Type...
A test of H0: μ = 50 versus H1: μ ≠ 50 is performed using a significance level of α = 0.01. The value of the test statistic is z = 1.23. a. Is H0 rejected? b. If the true value of μ is 50, is the result a Type I error, a Type II error, or a correct decision? A test of H0: μ = 50 versus H1: μ ≠ 50 is performed using a significance level of α...
Question 8 (1 point) A test is made of Ho: mean = 119 versus Hy: mean < 119. The true value of the mean is 103, and Ho is rejected. Is this a Type I error, Type II error, or a correct decision? O Correct decision Type Il error Type I error Question 9 (1 point) A test is made of Ho: mean = 0.94 versus H: mean > 0.94. The true value of the mean is 0.94, and Ho...
Question 6 (1 point) A test is made of Ho: mean = 27 versus Hi: mean < 27. The true value of the mean is 27, and Ho is rejected. Is this a Type I error, Type II error, or a correct decision? Type I error Type II error Correct decision O Question 7 (1 point) A test is made of Ho: mean = 71 versus Hii mean < 71. The true value of the mean is 35, and Ho...
2. If the test statistic for testing H0: µ≤ 10 vs. HA: µ > 10 at the .05 level is 1.641 and the sample size is 20, which of the following is true concerning the correct decision for the test, assuming that σ is unknown? A Type I error is possible A Type II error is possible Either a type I or II error is possible No error is possible 3. p-value for the test statistic
1. True or False: Detcrminc whether the following statements are true (T) or false F When the population standard deviation is known, a z-intcerval is used to calculase the confidence interval for the mean As the confidence level decreases, the wider the confidence interval becomes The best point estimate of the popalation mean is the sample mcan The probability of making a type I error is a and the probability of making a type II crror is B As a...
Determine whether the outcome is a Type I error, a Type II error, or a correct decision. A test is made of H0: μ = 67 versus H1: μ ≠ 67. The true value of μ is 68 and H0 is not rejected a)Type II error b)Type I error c)Correct decision
QUESTION 10 A test of Ho. u = 53 versus Hi: u<53 is performed using a significance level of a = 0.01 . The P-value is 0.046. If the true value of u is 46, does the conclusion result in a Type I error, a Type II error, or a correct decision? Type I error Correct decision OType II error
Determine whether the outcome is a Type I error, a Type II error, or a correct decision. A test is made of H0: μ = 40 versus H1: μ ≠ 40. The true value of μ is 40 and H0 is rejected. Group of answer choices Correct decision Type II error Type I error
