Q5) Here the test is a 2 tailed test as the alternative
hypothesis has a not equal to ()
sign.
Since the test statistic is negative, we first find the left tailed probability at z = -1.311 and then multiply by 2 to get the 2 tailed probability. At z = -1.311, the left tailed probability = 0.0949.
Therefore the required probability = 0.0949 * 2 =
0.1899
0.19 (Option 3).

Q6) Here the test is a left tailed test as the alternative hypothesis has a less than (<) sign.
We find the left tailed probability at z = -2.149 .
Therefore the required probability = = 0.0158
0.016 (Option 2).

help thank you :) Question 5 4 pts 5. In a test of hypotheses Ho :...
Hypotheses and summary sample statistics are given for a test for a proportion. Test Ho : p = 0.3 vs Ha :p>0.3 when the sample has p = 0.37 and n = 500. Find the value of the standardized z-test statistic and then use the standard normal distribution to find the p-value. Round your answers to three decimal places. z-test statistic - p-value = What is the conclusion using a 5% significance level? O Reject Ho O Do not reject...
In a test of hypothesis Ho: P = .31 versus Ha: P > .31 at the 1% level of significance a sample size of 1560 produced a p-hat(sample proportion) value of .34 and a test statistic z = 2.59. The p-value (observed significance level) of the test is about A 0.010 B 0.005 C 0.350 D 0.310 E 0.995
Use the t-distribution and the sample results to complete the test of the hypotheses. Use a 5% significance level. Assume the results come from a random sample, and if the sample size is small, assume the underlying distribution is relatively normal. Test H0 : μ=10 vs Ha : μ>10 using the sample results x¯=13.2, s=8.7, with n=12. test statistic = p-value =

4 pts Question 9 9. In a test of hypotheses H :u= 1873 vs. H:< 1873, the rejection region is the interval (-00, -2.896), the value of the sample mean computed from a sample of size 9 is m = 1792, and the value of the test statistic is t = -2.655. The correct decision and justification are Do not reject H, because the sample is small. Do not reject H, because -2.896 < -2.655. Reject...
How do you solve for the P-value?
In a hypothesis test with hypotheses Ho : j < 54 and H1 :u > 54, a random sample of 24 elements selected from the population produced a mean of 59.0 and a standard deviation of 14.0. The test is to be made at the 2.5% significance level. Assume the population is normally distributed. What is the critical value of t? 1.96 02.064 • 2.069 -2.069 What is the value of the test...
P-value is the probability, computed assuming H0 is true, that the test statistic would take a value as extreme or more extreme than that actually observed. Given the sample at hand, it is the smallest level of significance at which H0 would be rejected. It depends on the sample (hypotheses as well) and is hence also a test statistic. Generate 50 samples of size n=10 from a normal distribution with mean μ=1 and variance σ2=4. For each sample, use the...
Question 5 0/1 The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distribution. Test H0 : p=0.53 vs Ha : p≠0.53 when the sample has n=70, and p^=0.42 with SE=0.06. Find the value of the standardized z-test statistic. Round your answer to two decimal places.
Suppose you are testing the hypotheses Ho : p=0.21 vs. p +0.21 with significance level a = 0.05. A sample size of 209 results in a sample proportion of 0.26. As you know, one way to address two-sided tests is to create confidence intervals. Construct the appropriate confidence interval for p that could be used to address the test and report the upper limit of the confidence interval. Note: 1- Only round your final answer to 2 decimal places. Enter...
Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5% significance level. Test H0: p = 0.25 vs Ha: p < 0.25 using the sample results p̂p^= 0.13 with sample size n = 100. The standard error of the sample statistic in this situation is 0.043. Round your answer for the test statistic to two decimal places. What is the p-value?...
Question 4 0/3 pts 5399 Detail: You wish to test the following claim (H) at a significance level of a = 0.005. H: = 52.2 H: < 52.2 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 57 with mean M = 50.3 and a standard deviation of SD = 17.7. What is the test statistic for this sample? (Report answer accurate to three decimal places.)...
