Colonial Funds claims to have a bond fund which has maintained a mean share price of $9.00. They claim that the variance of the share price is0.16. To test this claim, the investor randomly selects 12 days during the last year. He finds an average share price of $8.80 with a standarddeviation of 0.3446. Can the investor conclude that the share price of the bond fund varies by less than Colonial Funds claims at a = 0.025?4Step 5 of 5: What is the conclusion?

Answered: al Funds claims to have a bond fund…

Which statement is not correct?A. Spurious correlation can often be reduced by expressing X and Y in per capita terms.B. Autocorrelation is mainly a concern if we are using time - series data.C. Heteroscedastic residuals will have roughly the same variance for any value of X.D. Standardized residuals make it easy to identify outliers or instances of poor fit. ( don't hand writing solution)
Executives of a supermarket chain are interested in the amount of time that customers spend in the stores during shopping trips. The mean shipping time, μ, spent by customers at the supermarkets has been reported to be 40 minutes, but executives hire a statistical consultant and ask her to determine whether it can be concluded that μ is less than 40 minutes. To perform her statistical test, the consultant collects a random sample of shopping times at the supermarkets. She computes the mean of these times to be 34 minutes and the standard deviation of the times to be 16 minutes. Based on the information, answer the questions below.
Executives of a supermarket chain are interested in the amount of time that customers spend in the stores during shopping trips. The mean shopping time, u, spent by customers at the supermarkets has been reported to be 35 minutes, but executives hire a statistical consultant and ask her to determine whether it can be concluded that u is greater than 35 minutes. To perform her statistical test, the consultant collects a random sample of shopping times at the supermarkets. She computes the mean of these times to be 42 minutes and the standard deviation of the times to be 10 minutes. Based on this information, answer the questions below. What are the null hypothesis (H,) and the alternative hypothesis (H,) that should be used for the test? H: u is ? H: u is ? In the context of this test, what is a Type I error? A Type I error is ? fact, u is ? ? v when, in v the hypothesis that u is? v? v. Suppose that the consultant decides to reject the null hypothesis. What sort of error might she be…
Assume that you have been provided the following information for a sample of cars The covariance between weight and miles per gallon is equal to -4.9 pound-miles. The standard deviation of the cars' mileages is 7.75. The standard deviation of the cars' weights is 0.94. Estimate the correlation coefficient to the first decimal place.
Professor Nord stated that the mean score on the final exam from all the years he has been teaching is a 79%. Colby was in his most recent class, and his class’s mean score on the final exam was 82%. Colby decided to run a hypothesis test to determine if the mean score of his class was significantly greater than the mean score of the population. α = .01. What is the mean score of the population? What is the mean score of the sample? Is this test one-tailed or two-tailed? Why?
Executives of a supermarket chain are interested in the amount of time that customers spend in the stores during shopping trips. The mean shopping time, µ, spent by customers at the supermarkets has been reported to be 40 minutes, but executives hire a statistical consultant and ask her to determine whether it can be concluded that u is greater than 40 minutes. To perform her statistical test, the consultant collects a random sample of shopping times at the supermarkets.

Assume that the following satisfaction scores of three companies for the 4th quarter of 2010 and 2011 were obtained from the Rochester's Customer Satisfaction Index. Assume that the scores are based on a poll of 100 customers from each company. Because the polling has been done for several years, the standard deviation can be assumed to equal 7 points in each case. (The scores on the following table are hypothetical values for the exam only) Company Costco BJ's Sam's 2010 Score 73 Ha: μ 1-μ 2 > 0 Ho: μ 1-μ 2 > 0 Ho: u 1-μ2=0 none of the above- Ha: μ 1-μ 2 <0 75 77 2011 Score 75 77 79 Professor Pan is interested in knowing whether the difference in the satisfaction score for Costco from 2010 to 2011 is statistically significant. assume a=5%, Professor Pan came up with the following hypotheses. Which of the following null or alternative hypotheses is correct?
