In a recent survey, the average amount of moneystudents have in their pockets is $5.40 with a standarddeviation of $1.20. A teacher feels that the averageamount is actually higher. She surveys 80 randomlyselected students and finds the average amount is$5.50. At α = 0.05, test the teacher’s claim that theaverage amount of money is actually higher than $5.40.

A study done in 1997 showed that 4.2% of mothers smoked cigarettes during their pregnancy. An obstetrician feels that this percentage is higher now. To test this, the obstetrician takes a sample of 200 mothers and finds that 10 of them smoked during their pregnancy. Test the obstetrician's claim at the a=0.05 level of significance.

10 veterans who suffer from PTSD are tested before and after taking an anti-anxiety medication thought to reduce PTSD symptoms. How do I report my findings in APA format? Before condition (M=52, SD= 13.4, SE=4.228) After condition (M=43, SD=13.4, SE=4.243) t(9)=1.581, p >0.05, d=0.500.
A repeated measures study with n=26 participants produces a mean difference of M D = 3 points, SS=500 for the difference scores, and t=2.50. Calculate Cohen's d and r square (r2) to measure the effect size for this study.
Interpret a P-value: The manufacturer of a medication designed to lower blood pressure claims that the mean systolic blood pressure for people taking their medication is less than 135. To test this claim, blood pressure is measured for a sample of 500 people who are taking the medication. The P-value for testing Ho: μ = 135 versus H₁: µ< 135 is P = 0.001. a. The manufacturer concludes that because the P-value is very small, we can be fairly certain that the mean pressure is less than 135, but we cannot conclude that it is a lot smaller. Is this conclusion justified?
State the t critical value that would be used for a 99% interval based on a sample size of 37.
In a survey of 1150 adult males, 805 said they use the Internet. In a survey of 1050females, 746 said they use the Internet. Atα= 0.05, can you reject the claim that the proportion of Internet users are the same for both groups?
A 2019 study surveyed Norwegian parents about their children's eating habits and taste sensitivities. We are interested in seeing if there is a relationship between sensitivity to sweetness and emotional overeating. The study reports an F* = 2.72 with df = 2 and dfw = 39. How many levels of 'sensitivity to sweetness' were used in the study? How many subjects participated in the entire study? Add Work
A magazine provided results from a poll of 1500 adults who were asked to identify their favorite pie. Among the 1500 respondents, 13% chose chocolate pie, and the margin of error was given as t4 percentage points. Describe what is meant by the statement that "the margin of error was given as ±4 percentage points." Choose the correct answer below. O A. The statement indicates that the interval 13% + 4% is likely to contain the true population percentage of people that prefer chocolate pie. O B. The statement indicates that the study is 100% - 4% = 96% confident that the true population percentage of people that prefer chocolate pie is 13%. C. The statement indicates that the study is only 4% confident that the true population percentage of people that prefer chocolate pie is exactly 13%. O D. The statement indicates that the true population percentage of people that prefer chocolate pie is in the interval 13% +4%.
NASA is conducting an experiment to find out the fraction of people who black out at G forces greater than 6 Step 1 of 2 : Suppose a sample of 595 people is drawn. Of these people, 315 passed out at G forces greater than 6. Using the data, estimate the proportion of people who pass out at more than 6 Gs. Enter your answer as a fraction or a decimal number rounded to three decimal places.
A researcher collected data from a sample of correctional officers and found that, on average, they made 47,173 dollars a year with S=6,364. Assuming that their salaries were normally distributed what proportion of correctional officers make less than 40,000 dollars a year?
