- Use the symbol

- Use the symbol>=to denote greater than or equal ( with no space between them)

- use the wordnot=to denote not equal ( with no space between them)

- Use the word "Mue" if you want to refer to the population mean

-Use the word "X bar" if you would like to refer to the sample mean

- Use the word "Pi" if you would like to refer to the population proportion

- Use the letter "p" if you would like to refer to the sample proportion

QUESTION 2 After a financial analysis, the general manager of a large company decided that if more than 8% of potential buyers of a new product purchase that product, the company would show a profit. In a preliminary survey of 500 potential buyers, 56 people say that they will buy the product. Is there sufficient evidence at the 10% significance level that the product will produce a profit? Use the p-value = 0.004145 to take your decision a. Null Hypothesis: b. Alternative Hypothesis: c. P-value than a (WRITE either greater, less, or equal) d. Decision: (write the letter a if you will reject Ho or write the letter b if you will not reject HO, your answer should be either a or b) QUESTION 3 Using the test in the previous question, what conclusion can be drawn about the profit of the product For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).

For a random sample of 15 sails, the mean amount of material used is 912 square feet. Find a 90% confidence interval for the population mean amount of material used in a custom sail. a. Point estimate value = b. Standard error (approximate to four decimal points) = c. Margin of error (approximate to four decimal points) = d. Tabulated value (approximate to four decimal points) = e. Upper limit (approximate to four decimal points) = f. Lower limit (approximate to four decimal points) =QUESTION 5 Interpret the confidence interval calculated in the previous question For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
