A soft-drink manufacturer claims that its 12-ounce cans do not contain, on average, more than 30 calories. A random sample of 16 cans of this soft drink, which were checked for calories, contained a mean of 31.8 calories with a standard deviation of 3 calories. Assume that the number of calories in 12-ounce soda cans is normally distributed.
a) State the null and alternative hypotheses.
b) Select the distribution to use. Explain briefly why you selected it.
c) Assuming that they wish to test the claim at alpha = 0.025, determine the rejection and non rejection regions based on your hypotheses in a). State the critical value.
d) Calculate the value of the test statistic.
e) Does the sample information support that the manufacturer's claim is false? Explain your conclusion in words.
How would you find the normal approximation to the binomial probability P(x = 5) in part A? Please show how you would calculate µ and σ in the formula for the normal approximation to the binomial, and show the final formula you would use without g..
A player of a video game is confronted with a series of opponents and has an 80% probability of defeating each one. Success with any opponent is independent of previous encounters. The player continues to confront opponents until defeated.
The annual income of a large group of supervisors at Belco Industries follows the normal distribution. The mean amount earned yearly is $48,000 and the standard deviation is $1,200.

Using the 0.10 level of significance, is there evidence that the mean shopping time at the local supermarket is greater than the claimed value of 22 minutes?
Using a spreadsheet, create a table that shows the relationship among the units of heights of people in centimeters, inches and feet in the range of 150cm to 2m. Use increments of 5cm.
Determine a 95% confidence interval for true time battery pack can function before having to be recharged.
A "one-shot" device can be used only once; after use, the device (e.g. a nuclear weapon, space shuttle, automobile air bag) either is destroyed or must be rebuilt.
The speed with which utility companies can resolve problems is very important. GTC, the Georgetown Telephone Company, reports they can resolve customer problems the same day they are reported in 70 percent of the cases.
What is the smallest level of significance at which you could reject the null in favor of the alternative hypothesis?
A confidence interval estimate for the population mean is given to be (40.45, 49.24). If the standard deviation is 11.159 and the sample size is 35, answer each of the following (show all work):
