A well-known diet doctor has developed a new formula for a drug that will suppress appetites.The Food and Drug Administration (FDA) wants this doctor to submit research to show thatthere is a significant difference in weight loss for patients using the new drug versus the olddrug. Which of the following would be the best method to obtain results the FDA isrequesting?The doctor assigns the new drug to patients who have more than 10 pounds to lose and the old drug topatients with less than 10 pounds to loseThe doctor should randomly assign patients to two groups: one group takes the new drug and the othergroup takes the old drug.The doctor should randomly choose patients and allow them to select which drug they want to use.The doctor should randomly choose patients to take the new drug and ask patients using the old drug howmuch weight they have lost.57A data set has numbers: 3, 5, 5, 6, 4, 3, 1, and 7. Which is the interquartile range? *3.02.02.5

Can you please answer all of the questions about the information provided. Background Previous studies have demonstrated the short-term efficacy of pharmacotherapy and behavior therapy for attention-deficit/hyperactivity disorder (ADHD), but no longer-term (ie, >4 months) investigations have compared these 2 treatments or their combination. A 1999 study conducted by MTA Cooperative Group conducted a multisite study designed to evaluate the leading treatments for ADHD. The Study A group of 425 children with ADHD Combined Type, aged 7 to 11 years, were assigned to 14 months of medication management (titration followed by monthly visits); intensive behavioral treatment (parent, school, and child components, with therapist involvement, gradually reduced over time); or the two combined. Outcomes were assessed in multiple domains before and during treatment and at the treatment endpoint (with the combined treatment and medication management groups continuing medication at all assessment…
Twenty years ago, 51%of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 237 of 750parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did twenty years ago? Use the α=0.01 level of significance.
A certain training device measures reaction times of users by illuminating lights, one at a time, and measuring the time it takes the user to press each light to turn it off. The makers of the device are marketing it for high-level training, saying that even among professional athletes, the proportion who can score the top ranking of "light speed" is less than 22% . As a fitness trainer who wants to buy the device to attract more customers, you want to feel comfortable that the claim made by the makers is correct. To test the claim, you decide to perform a hypothesis test. To do so, you rent the device and have a random sample of 130 professional athletes use it; 26 score a ranking of "light speed." You confirm that it is appropriate to perform a Z -test. Why is a Z -test appropriate? Find z , the value of the test statistic for your Z -test. Round your answer to three or more decimal places. =z

A manufacturer wants to increase the shelf life of a line of cake mixes. Past records indicate that the average shelf life of the mix is 231 days. After a revised mix has been developed, a sample of nine boxes of cake mix gave these shelf lives (in days): 230,233, 235, 236, 233, 240, 240, 241, and 237. Using α = 0.025, has the shelf life of the cake mix increased? Multiple Choice Yes, because computed t is greater than the critical value. Yes, because computed t is less than the critical value. No, because computed t lies in the region of acceptance. No, because 236.11 is quite close to 231.

Confidence in banks: A poll conducted in 2012 asked a random sample of 1217 adults in the United States how much confidence they had in banks and other financial institutions. A total of 160 adults said that they had a great deal of confidence. An economist claims that greater than 11% of U.S. adults have a great deal of confidence in banks. Can you conclude that the economist's claim is true? Use both =α0.05 and =α0.10 levels of significance and the P-value method with the TI-84 Plus calculator. (a) State the appropriate null and alternate hypotheses. :H0 :H1
BREAKFAST AND TEST SCORES 1 of 4 What type of test should this researcher use? Conventional wisdom says that eating a healthy breakfast can improve your health and your weight, but can it also affect your test scores? In order to test this, a school program convinces a group of students to skip breakfast one morning before taking a Basic English test. Eighteen students received breakfast before taking the test, and twenty-one students did not eat breakfast and recorded their performance on the English test. What type of research test should this researcher use? Their results are as follows:
