NEW STUDY: Dr. Apnea conducted a study investigating the effects of sleep deprivation on complex problem solving. He gave 25 college students a problem-solving test at noon on one day and a second problem-solving test at noon the following day. He found that there was a statistically significant mean decrease of 4.7 between the two tests from the first day to the second day. The test yielded a Cohen’s d = .82. Which of the following statements is an accurate interpretation of Dr. Apnea’s research? Group of answer choices It doesn’t matter how much sleep you get, some people just aren’t good at problem solving. If you don’t get enough sleep your problem solving abilities suffer, but only with a small absolute magnitude. If you don’t get enough sleep your problem solving abilities suffer with a medium absolute magnitude. If you don’t get enough sleep your problem solving abilities suffer with a large absolute magnitude.
Calvin thinks a certain potato chip maker is putting fewer chips in their regular bags of chips. From a random sample of 13 bags of potato chips he calculated a P value of 0.048 for the sample. (a) At a 5% level of significance, is there evidence that Calvin is correct? (Type: Yes or No): equation editor (b) At a 10% level of significance, is there evidence that he is correct? (Type: Yes or No): equation editor (c) In a statistical test of hypotheses, we say that the data are statistically significant at level α� ifA. the P - value is larger than α�.B. α� is small.C. α=0.05�=0.05.D. the P - value is less than α�.

I am having trouble solving this problem. Can you please provide me with some help? Thank you. I appreciate it. Almonte. Inc., a maker of low-priced hair care products, claims that its hair spray lasts as long as the industry leader's higher-priced product. You take a sample of 60 applications of Almonte's hair spray and 60 applications of the leading hair spray. Results: On average, the Almonte applications held for 12.7 hours with a standard deviation of 1.4 hours. On average, the leading hair spray lasted 11.8 hours with a standard deviation of 1.8 hours. Set up a hypothesis test to test whether the difference in sample means is statistically significant. Use a significance level of 1%. Report and explain your conclusion.
Would you favor spending more federal tax money on the arts? Of a random sample of n1 = 86 politically conservative voters, r1 = 18 responded yes. Another random sample of n2 = 85 politically moderate voters showed that r2 = 21 responded yes. Does this information indicate that the population proportion of conservative voters inclined to spend more federal tax money on funding the arts is less than the proportion of moderate voters so inclined? Use α = 0.05. (a) State the null and alternate hypotheses.

A telemarketer is trying two different sales pitches to sell a carpetcleaning service. For Sales Pitch I, he contacted 175 people and 62 of these people bought the cleaning service. For Sales Pitch II, he contacted 154 people and 45 of these people bought the cleaning service. Does this indicate that there is any difference in the population proportions of the people who will buy the cleaning service, depending on which sales pitch he uses? Use α = 0.05.
A Biology 20 class wanted to investigate the endurance of fellow students related to the activity of muscle cells. A muscle is said to be fatigued when it is unable to maintain a certain level of performance. The students designed an experiment that used the number of repetitions of a muscle group to indicate the level of performance. Procedure: Each individual used the apparatus diagrammed above to perform three trials. First a 250 gram load was used, then 500 grams, and lastly a 1000 gram load was used. A 1 litre soft drink bottle was filled with the appropriate mass of water. (1 mL of water = 1 gram). The subject was instructed to raise and lower each mass rapidly -- about twice a second. The trial was considered finished if the subject could not raise the weight 3 cm or was unable to maintain a rate of 2 lifts per second. Between trials the subject had a 1 minute rest. During this time the arm of the subject could be massaged. I Questions: (a) What problem were the Biology 20 class…
Frankenstein has conducted a study to see if children who “can’t say something nice” (group A) get more candy than children who “don’t say nothing at all” (group B). He observed that, on average, group A gets 19 pieces and group B gets 23 pieces. Dr. Frankenstein then ran a t-test, in which he found t(20) = 2.536. How should Dr. Frankenstein interpret his findings? (Hint: It may help to look at how t-scores are reported in APA format.)
Do you prefer paintings in which the people are fully clothed? This question was asked by a professional survey group on behalf of a national arts organization. A random sample of n1 = 58 people who are conservative voters showed that r1 = 45 said yes. Another random sample of n2 = 64 people who are liberal voters showed that r2 = 39 said yes. Does this indicate that the population proportion of conservative voters who prefer art with fully clothed people is higher? Use α = 0.05.
