A manufacturer of chocolate candies uses machines to package candies as they move along a filling line. Although the packages are labeled as 8 ounces, the company wants the packages to contain a mean of 8.17 ounces so that virtually none of the packages contain less than 8 ounces. A sample of 50 packages is selected periodically, and the packaging process is stopped if there is evidence that the mean amount packaged is different from 8.17 ounces. Suppose that in a particular sample of 50 packages, the mean amount dispensed is 8.171 ounces, with a sample standard deviation of 0.052 ounce.1. Is there evidence that the population mean amount is different from 8.17 ounces? (Use a 0.01level of significance.)2. State the null and alternative hypotheses. H0:μ ( ≥, ≤, =, <, >,≠) H1:μ ( ≥, ≤, =, <, >,≠) (Type integers or decimals.)3. The critical value(s) is(are) (Round to four decimal places as needed. Use a comma to separate answers as needed.)4. The test statistic is (Round to four decimal places as needed.)5. Reject/ Do not reject H0. There is sufficient/insufficient evidence to conclude the population mean amount is different from 8.17ounces.6. The p-value is (Round to four decimal places as needed.)7. Interpret the meaning of the p-value. Choose the correct answer below. A. The p-value is the probability of obtaining a sample mean that is equal to or more extreme than 0.001 ounce below 8.17if the null hypothesis is false. B. The p-value is the probability of obtaining a sample mean that is equal to or more extreme than 0.001 ounce away from8.17 if the null hypothesis is true. A. The p-value is the probability of obtaining a sample mean that is equal to or more extreme than 0.001ounce aboveB. The p-value is the probability of not rejecting the null hypothesis when it is false.

Jenny invests $2,000 at an interest rate of 5%. the amount of money, me, in jenny's account after tyears can be represented using the equation ma-2000(1.05). if jenny would have invested the same amount of money at the same interest rate four years ago, the equation representing the amount of money mo. in her account would be represented using the equation! mg = 2000(105)*** which of the following is equivalent to mp? 2000(105) om- 1.05 2000(1.05) mo 1059 mp-2000(1.05) (105) mp - 2000(1.05) + (1.05)
