If the attachment picture answer is correct (if not, what is the answer & how did you get the answer) In the Invisible Gorilla experiment, the assumption is that most observers in this experiment would notice a person in a Gorilla suit walk into the middle of the ball tossers, beat their chest, and walk out. In our hypothetical example, H0 = The relative frequency of successes in the population is p = 0.75 (ie, most observers) HA = The relative frequency of success in the population is something other than p = 0.75 (p ≠ 0.75) In looking at your calculated 95% confidence interval (assuming your answer is correct), does the value of 0.75 fall inside or outside of the interval? Would you then reject or fail to reject the null hypothesis? (select all that applies) inside outside reject fail to reject
Hey, can you show me how to calculate part B in the attached problem?
The hypothesis should revolve around one of the variables collected for all subjects. Your results section should describe the general course of one subject’s response from your individual analysis and then evaluate your hypothesis for a specific collective variable. Please explain this in plain english. I dont understand the instructions. Here is a reference of the subjects.

QUESTION 2 To test the effect of a new medication on pulse rate, the researcher randomly selected the 60 subjects into two groups of 30. New medicine and placebo were given to Group 1 and Group 2, respectively. Below is the Minitab output. Two-Sample T-Test and CI Group 1 N Мean StDev 7.80 SE Mean 30 65.20 1.4 2 30 70.30 8.40 1.5 Difference = mu (1) - mu (2) Estimate for difference: -5.10 95% CI for difference: (-9.29, -0. 91) T-Test of difference = 0 (vs not =): T-Value = -2.44 P-Value=0.018 DF=57 i) State the formula you would use to construct a 95% confidence interval. Include the value of a and degrees of freedom that you will use to find the critical value in the formula
Question #1 You observe the following data that represents the average outcomes of two groups of individualsthose who received an intervention ("Treated") and those who did not (“Not Treated")-over two periods before the treated group received the intervention and after. Group Treated Not Treated Before After 75 30 40 20 Compute the pre-/post- (BTs), cross section (Bxs), and difference-in-differences (Bpp) estimators of the causal impact of treatment.
QUESTION 2 To test the effect of a new medication on pulse rate, the researcher randomly selected the 60 subjects into two groups of 30. New medicine and placebo were given to Group 1 and Group 2, respectively. Below is the Minitab output. Two-Sample T-Test and CI Group Мean StDev SE Mean 1 30 65.20 7.80 1.4 2 30 70.30 8.40 1.5 Difference = mu (1) - mu (2) Estimate for difference: 95% CI for difference: T-Test of difference = 0 (vs not =): T-Value = -2.44 -5.10 (-9.29, -0.91) P-Value=0.018 DF=57 ii) Using to.025,57 = 2.003 shows that the 95% confidence interval for the difference in mean pulse rate between new medication and placebo is (-9.29, -0.91). Hence, interpret its meaning.

Question 3 > Which of the following statements is false about the principles of a good experiment? O Studying many cases (e.g. including many patients in a study) is often more helpful than just including a few cases in the study. O Using a control group with a placebo is important since otherwise subjects in the control group may behave differently than these in the treatment group. O If we collect more information on each case (e.g. take repeated measurements on each individual) that might be helpful to obtaining more precise results in an experiment. OWe can always generalize the result of a study to the greater population so long as we randomize which patients go into which study groups. Randomizing individuals into groups is one way of preventing accidental bias from creeping into a study. Considering (controlling) more variables in planning an experiment helps ensure each study group is similar to the other study groups. > Next Question étv 18 & % %24 8. 9. 6 7 4.
