- A pharmaceutical company wanted to study the effectiveness of a new hair growth product in women. It recruited 1100 random women from the L.A. area and measured the length of their hair. They gave 500 women the new product in unmarked bottles to use over a 6-month period. The other 600 women received unmarked bottles with mostly water and fragrance to use over a 6-month period. None of the women knew which product they received. They found that 450 out of 500 women that received the new product showed hair growth of 1-2 inches. Only 90 out of 600 women that used the water/fragrance combination showed hair growth of 1-2 inches. What percentage of women that received the treatment showed hair growth of 1-2 inches? Answer: 450/ 500= 0.9= 90%Explain the Extended Least Squares Assumptions?A team of social workers wants to compare the different effects of treatments for complex trauma. They divide 21 clients into 3 groups (n=7 each) that donot differ significantly from one another in terms of pretreatment trauma. one group gets (TFCBT), one group gets (EGT) and one receives a combination of the two (TF+EG). Clients symptoms are evaluated after treatment using a clinician interview where scores from range from 0-30 and higher scores indicate a higher severity. What test should be ran to see if there is a difference in post-treatment scores among the three treatments, and what graph should I use?
- Please show clear and complete solution! last 30 minutes left Thank you!how to write a null and alternative hypothesis that can be tested using regression test in SPSS software?A laboratory research group did a microarray experiment five years ago with 10 subjects in the normal group, and 6 subjects in the diet group; one microarray per subject. They never published their results because they felt like their diet group was too small. Now they have more money and they want to get 4 diet animals, and run 4 new microarrays on those animals. They plan to add that data to their study so they can increase their statistical discovery power, and finally publish their results. Although increasing the number of subjects should increase the statistical power of the study, give a reason why increasing the number of samples might NOT result in more significant results.

A manager is trying to educate employees on the effects of personal health and workplace performance. The manager has gathered data from a group of employees to evaluate the effects of sleep and sickness. The manager asked employees to record the total number of hours of sleep they had over 10 working days in two weeks and compared it to the number of sick days that each took over those 10 days. Sick Days Total hours of sleep 0 80 2 40 1 60 0 70 3 50 2 90 4 35 1 68 0 72 2 55 Is the model statistically significant at the .05 level?

- Find the least square regression line for set of points {(1,3), (2,4), (3,4), (4,6)}Imagine you need to come up with a diagnostic test to monitor the viral load of patients with HIV. If the viral load is higher than a set standard, there is evidence the anti-retroviral therapy is no longer working and the patient needs to be moved to a different therapy that costs more money. Thus, false positives incur higher costs. However, if the test misses higher than normal viral loads (for patients in treatment), then the patient runs the risk of developing AIDS. Hence, false negatives result in a likely deadly disease. How would you balance these two types of error in devising your test? Minimize beta by raising the one-tailed alpha, since greater power will reduce false negatives and save patients O Minimize the one-tailed alpha, since lower P-values indicate the test is highly significant and prevent prematurely switching the patients Minimize the one-tailed alpha and beta, since this action will prevent prematurely switching the patients and reduce false negatives, thereby…why is the DV female drosophila Do you use a z or test for this problem?
