2. Use the following scenario to conduct a hypothesis test. Then use that to answer questions a- g. You would like to determine if the use of a new teaching intervention helps to improve attention in 5- year-old boys. To test this hypothesis, you have separated 35 5-year-old boys into two groups, one with the intervention (treatment group) and the other given normal class time (the control group). You would like to test if the treatment group had longer attention times (in minutes) than the control group. (The significance level of the test is .05) The following are the data for the two groups: Control Group (Group 1) 7 11 6 6 8. 11 14 7 8. 2 Treatment Group (Group 2) 11 12 14 16 18 14 11 8 7 10 11 Answer the following questions to run the hypothesis test. You should use the notation and methods described in the course: a. What test should you run? b. What is the null hypothesis in sentences and symbols? c. What is the alternative hypothesis in sentences and symbols? d. What is the…

Hypothesis testing will consist of four hypothesis tests which you need to complete. each test will require the following: Type of Test: Null Hypothesis: Alternate Hypothesis: SE: Test Statistic: P-value: Decision: Sentence:
This type of error in hypothesis testing is also known as a “false positive” result.A. Type IB. Type AC. Type IID. Type B
What are the two decisions that you can make from performing a hypothesis test? What are the two decisions that you can make from performing a hypothesis test? Select all that apply. A. reject the alternative hypothesis B. make a type I error C. accept the alternative hypothesis D. reject the null hypothesis E. accept the null hypothesis F. fail to reject the alternative hypothesis G. fail to reject the null hypothesis H. make a type II error

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.
Food inspectors inspect samples of food products to see if they are safe. This can be thought of as a hypothesis test with the following hypotheses. H0: the food is safe Ha: the food is not safe The following is an example of what type of error? The sample suggests that the food is safe, but it actually is not safe. Choose one below a. type I b. type II c. not an error
Show your complete solution II. Use an appropriate statistical tool to test the hypothesis. Use the stepwise method of hypothesis testing. 3. A researcher observed that students preferred several online class platforms. For this reason, he performs a survey to know whether or not gender is associated with online class platforms preference and he was able to gathered the following data Zoom Google Meet MS Teams Total Male 110 95 40 245 Female 105 100 50 255 Total 215 195 90 500
