Español Valley College and Elm College are two local colleges. For each college, the distribution of the ages of faculty members is clearly bell-shaped. The ages of faculty members at Valley College have a population mean of 51 years and a standard deviation of 6.3 years. The ages of faculty members at Elm College have a population mean of 56 years and a standard deviation of 4.2 years. Maria is 67 years old and a faculty member at Valley College. Salma is 40 years old and a faculty member at Elm College. (a) Find the z-scores of Maria's age as a faculty member at Valley College and Salma's age as a faculty member at Elm College. Round your answers to two decimal places. z-score of Maria's age: z-score of Salma's age: (b) Relative to her population, who is the older faculty member?

Suppose that Jett achieves a score of 1250 on the SAT, and his sister Kate scores 29 on the ACT. The SAT scores are normally distributed with a mean of 1100 and standard deviation of 250. The ACT scores are normally distributed with a mean of about 20 and standard deviation of 5. Who did better, relative to their peers?
You hypothesize that people in stats classes are happier than people in all other classes. You compare happiness scores in three of your classes: Statistics, Developmental Psychology, and Social Psychology. In Statistics there are 15 students and the mean happiness rating is 23.1 with a standard deviation of 9.78. In Developmental Psychology there are 15 students and the mean happiness rating is 24.4 with a standard deviation of 2.92. In Social Psychology there are 15 students with a mean rating of 17.7 and standard deviation of 8.46. The sum of squares between groups is equal to 384. The sum of squares within groups is equal to 2461. Use the One-Way ANOVA calculation table to help calculate. What is the degrees of freedom between samples?

Insurance companies make bets. They bet that you’re going to live a long life. An insurance company offers a “death and disability” policy that pays average of $10,000 when you die with a standard deviation of $1,000 or pays average $5000 if you are permanently disabled with standard deviation of $1,000. Assuming the distribution of the policy payout is normal. What percentage of pay will lie between payout of $7,000 and $9,000 when you die? What percentage of the payout will lie below $7,500 if you are permanently disabled? What percentage of the policy will lie above $8,100 when you die?
A mechanic sells a brand of automobile tire that has a life expectancy that is normally distributed, with a mean life of 36,000 miles and a standard deviation of 2100 miles. He wants to give a guarantee for free replacement of tires that don't wear well. How should he word his guarantee if he is willing to replace approximately 10% of the tires? Click to view page 1 of the table. Click to view page 2 of the table. CHE Tires that wear out by miles will be replaced free of charge. (Round to the nearest mile as needed.)
Newborn babies: A study conducted by the Center for Population Economics at the University of Chicago studied the birth weights of 716 babies born in New York. The mean weight was 3506 grams with a standard deviation of 868 grams. Assume that birth weight data are approximately bell-shaped. Estimate the number of newborns who weighed between 1770 grams and 5242 grams. Round to the nearest whole number. The number of newborns who weighed between 1770 grams and 5242 grams is

Answer quickly please. Need answer ASAP. A study was made to determine if the subject matter in a physics course is better understood when a lab constitutes part of the course. Students were randomly selected to participate in either a 3-semester-hour course without labs or a 4-semester-hour course with labs. In the section with labs, 17 students made an average grade of 85 with a standard deviation of 4.7, and in the section without labs, 17 students made an average grade of 79 with a standard deviation of 6.1. Construct 90% confidence interval for the difference of the mean grades between the two physics courses. Based on your interval, would you say that the laboratory course increases the average grade? Assume the populations to be approximately normally distributed.
