using the sequential step of hypothesis testing It has been known that a fixed dose of a certain drugcauses an average increase of pulse rate of at least 12beats per minute with a standard deviation of 5. Agroup of 20 patients given the same dose showed thefollowing increases.15, 10, 14, 16, 7, 12, 8, 15, 11, 13,9, 12, 9, 17, 15, 10, 11, 10, 14,7Is there evidence to show that this group has alower average increase of pulse rate than the ones ingeneral? Use a - 0.05.

hii! can someone help with this? thank you!!
Español Try Again Your answer is incorrect. The proportion of residents in a community who recycle has traditionally been 65%. A policy maker claims that the proportion is less than 65 % now that one of the recycling centers has been relocated, and the policy maker wishses to carry out a hypothesis test. State the null hypothesis H, and the alternative hypothesis H, that the policy maker would use for this test. Ho: 0.65 Aa H: 0.65 S O
Using the P-value method decide if you should reject the null hypothesis or not. In a sample of 81 adults selected randomly from one town, it is found that 8 of them have been exposed to a particular strain of the flu. At the 0.01 level of significance, you wish to test the proportion of all adults in the town that have been exposed to this strain of the flu is 8%
K The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a= 0.01, (b) a = 0.05, and (c) a = 0.10. P=0.0647 .. (a) Do you reject or fail to reject Ho at the 0.01 level of significance? OA. Reject Ho because the P-value, 0.0647, is greater than α=0.01. O B. Fail to reject Ho because the P-value, 0.0647, is less than α = 0.01. O C. Fail to reject Ho because the P-value, 0.0647, is greater than a = 0.01. OD. Reject Ho because the P-value, 0.0647, is less than a = 0.01. (b) Do you reject or fail to reject Ho at the 0.05 level of significance? OA. Fail to reject Ho because the P-value, 0.0647, is greater than α=0.05. OB. Reject Ho because the P-value, 0.0647, is greater than a = 0.05. OC. Reject Ho because the P-value, 0.0647, is less than a = 0.05. O D. Fail to reject Ho because the P-value, 0.0647, is less than a = 0.05. (c) Do you reject or fail to reject Ho at the 0.10 level of significance? 1
Hypothesis Test: Perform the specified hypothesis test. Be sure to include your statistical andin-context conclusion statements. In 1994, 52% of parents with children in high school felt it was a serious problem that high schoolstudents were not being taught enough math and science. A recent survey found that 512 of 1000 parentswith children in high school felt it was a serious problem that high school students were not being taughtenough math and science. Do parents feel different today than they did in 1994? Use the α = 0.005significance level.
Quesiton 43
The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a= 0.01, (b) a=0.05, and (c) a= 0.10. P=0.0596 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? OA Fail to reject Hg because the P-value, 0.0596, is greater than a= 0.01. OB. Reject Ho because the P-value, 0.0596, is greater than a= 0.01. OC. Fail to reject Hg because the P-value, 0.0596, is less than a=0.01. %3D OD. Reject Ho because the P-value, 0.0596, is less than a= 0.01. %3D
explain please
H0: p1=p2 H1: p1<p2 1) Identify the test statistic. 2)Identify the P-value.
