For questions 10-18, use the following example:Multiple studies have found that speaking curse words can reducethe sensation of pain (Stephens et al., 2009). A researcher learns thatthe mean pain score in the population is 6.0 on a 10-point scale(where 1 is the lowest pain score, and 10 is the highest pain score),with a standard deviation of 1.0, when people submerge their handsinto ice cold water without saying any curse words. The researcherselects a random sample of 81 college students at SDSU and asksthem to submerge their hands in ice cold water for 5 minutes whilerepeatedly saying their favorite curse word. The mean pain score forthe sample of students who participated in this experiment was 5.7.13What will the shape of the sampling distribution be? Why?XBBTU Ax, E 12ptEA IEEEYParagraphY

Question 2: A student safety advocacy group believes that drivers are speeding down Manhattan College Blvd. To prove their point, they wish to college vehicle speed data. Previous research has shown that the standard deviation of vehicle speeds on this functional class of roads is 7.00 mph. A. How many vehicles will the group need to sample to determine the 50h percentile speed if they wish to be 95.5% confident in their results plus or minus 3.00 mph? B. How does the 50th percentile required sample size change if we are concerned about the 85th percentile? C. How does the 50h percentile required sample change if we want the results to be accurate to plus or minus 1.5 mph?

Consider the data from the Anthropology 105 class. The mean for women is 64.33 in and the standard deviation is 2.64 in. The average height of men in the US is approximately 5ft 10in. What proportion of women represented here are shorter than the average man?
QUESTION 1 A health researcher read that a 150-pound college-aged, male can burn an average of 530 calories per hour playing tennis with a standard deviation of 25 calories. 40 college-aged males were randomly selected at a commuter school and the mean number of calories burned per hour playing tennis was 540 calories. Do college-aged male tennis players at the commuter school burn more calories per hour than the college-aged, male tennis player population? Test with a 0.05 significance level. What are the hypotheses? Null and Alternate
The mean salary at a local industrial plant is $29,600 with a standard deviation of $5700. The median salary is $25.300 and the 59th percentile is $30,200. Step 5 of 5: If Tom's salary has a z-score of 0.6, how much does he earn (in dollars)?
QUESTION 8 You are interested in seeing whether emotions impact decision making. You have three groups--a happy group, a sad group, and a neutral group. For the happy group there are 5 participants and the mean risky decision making score 5.0 with a standard deviation of 0.7. For the sad group there are 5 participants and the mean risky decision making score 5.4 with a standard deviation of 1.1. For the neutral group there are 5 participants and the mean risky decision making score 5.8 with a standard deviation of 2.8. The sum of squares between samples is equal to 1.6. The sum of squares within samples is equal to 38.0. What is the degrees of freedom total? Please do the calculations on the handout provided.

Imagine that a study of memory and aging finds that younger participants correctly recall 55% of studied words, older participants correctly recall 42% of studied words, and the size of this effect is Cohen's d = 0.49. This effect size indicates that the memory performance of: Question 10 options: younger participants is approximately half a standard deviation below that of older participants. older participants is approximately half a standard deviation below that of younger participants. younger participants is significantly lower than that of older participants. older participants is approximately 4 standard deviations below that of younger participants.
QUESTION 6 The Corner Drug Store fills prescriptions for a popular children's antibiotic, amoxicillin. The daily demand for amoxicillin is normally distributed, with a mean of 200 kilograms and a standard deviation of 80 kilograms. The vendor for the pharmaceutical firm that supplies the drug calls the drugstore pharmacist every 30 days to check the inventory of amoxicillin. During a call, the druggist indicated that the store had 60 kilograms of the antibiotic in stock. The lead time to receive an order is 4 days. a) Determine the order size that will enable the drugstore to maintain a 95% service level.
Suppose there is a city where the mean cost per month of a one-bedroom apartment is $1,500, with a standard deviation of $250. Approximately what percentage of one-bedroom apartments in the city cost between $750 and $1,000?
Step 1: Read each situation Situation 1: One survey on runners in a marathon was made, and it was found out that 18% of runners take energy gels during a marathon. One runner wanted to test the claim. A random sample of 56 runners were asked, and 24% of them said that they take energy gels during a marathon. The standard deviation is 10. The significance level is 0.01. Situation 2: Based on one research, it is said that at most 75% of people migrating abroad with a different climate gets sick on their first month. To verify this claim, a sample of 260 people who migrated abroad were asked, and 68% of them said that they got sick during the first month of their stay. The standard deviation is 50. The significance level is 0.10. Situation 3: A wonder drug that cures cancer was recently released. The company claims that it is at least 86% effective. A random sample of 550 cancer patients were asked, and 90% of them said that it was effective. The standard deviation is 100. Use a…
