8. A stock market analyst believes that the average price of two securities (Stock A and Stock B) are equal. The analyst does not know the population standard deviation of the two securities. The following information outlines the information for each sample: Stock A Stock B ni = 8 n2 = 13 Xi= $86 X2= $94 !! s1= $4 52=$12 Assuming that the population variances are not equal, test the analyst's claim at the 0.01 level 9. Using the information in the previous question (Question 8), test to see whether the population variances are equal or not equal at the 0.05 level.

SWC surveyed its students and measured the extent of their tendency to conform to others on a scale of 1 to 10. Higher scores indicate a higher tendency to conform. The mean score for students at the college was 6 with a standard deviation of 2. Professor Hayashi believes his students are very independent. He measures the conformity of his students on the same scale to see if they differ from the college. The following scores are the conformity scores of the sample of students: 4 7 5 4 3 10 7What proportion of random samples of students score between Professor Hayashi’s class and the population mean?
The mean weekly earnings of all female workers in a state is $710 and the mean weekly earnings of all male workers in the same state is $760. The standard deviations of the weekly earnings are $86 for the females and $106 for the males. Suppose we take one sample of 316 female workers and another sample of 329 male workers from this state. 1.1. By hand, what is the mean of the sampling distribution of the difference between the mean weekly earnings for females and males? 1.2. By hand, what is the standard deviation of the sampling distribution of the difference between the mean weekly earnings for females and males, rounded to two decimal places?
3. The distribution of test scores in a class is unimodal and symmetric with a mean of 80 pts and a standard deviation of 7pts. Based on the information, Adam estimated that his score is higher than approximately 97.5% of the students in class. What score did Adam receive? Explain.

(AKS 24): A technology magazine finds data that suggests the prices of computers with a specific configuration follow an approximately normal distribution with a mean of $892.22 and a standard deviation of $109.30. What percentage of these computers are priced higher than $950?
Suppose the weights of 3-month-old babies are normally distributed—baby boys with a mean of 14.3 pounds and a standard deviation of 1.7, and baby girls with a mean of 12.7 pounds and a standard deviation of 1.7. What proportion of 3-month-old baby girls will weigh between 12 and 13 pounds? (Round your answer to four decimal places.)
The empirical rule states that the percentage of observations in a data set (provided that the data set has a bell-shaped and symmetric distribution) that fall within one standard deviation of their mean is approximately 75%. TRUE OR FALSE
For college-bound seniors in 2018, SAT math scores are normally distributed with a mean of 515 and a standard deviation of 116. You suspect that seniors in the Auraria Campus are much brighter than the country as a whole, so you decide to conduct a test. In a random sample of 25 seniors, you find the mean SAT math score to be 555. You assume that the standard deviation of math scores in Auraria Campus are the same as the national standard deviation of a = 116. Is this sufficient evidence to conclude that Auraria Campus seniors are smarter? Take a -0.05.
Mf1. 7. Consider the following returns: (1) What are standard deviations of stock X and stock Y respectively? (2) What are is the correlation between stock X's return and stock Y's return? (3) Please estimate the return and standard deviation of the combination of stock X and stock Z in the equal shares
The salaries of professional baseball players are heavily skewed right with a mean of $3.2 million and a standard deviation of $2 million. The salaries of professional football players are also heavily skewed right with a mean of $1.9 million and a standard deviation of $1.5 million. A random sample of 40 baseball players’ salaries and 35 football players’ salaries is selected. The mean salary is determined for both samples. Let represent the difference in the mean salaries for baseball and football players. Which of the following represents the shape of the sampling distribution for ? skewed right since the populations are both right skewed skewed right since the differences in salaries cannot be negative approximately Normal since both sample sizes are greater than 30 approximately Normal since the sum of the sample sizes is greater than 30
