  1. You represent a chemical company that is being sued for paint damage to automobiles. You want to support the claim that the mean repair cost per automobile is more than $650. How would you write the null and alternative hypotheses?

State the null and alternative hypotheses in words (context of the problem)

Write the null and alternative hypotheses in appropriate symbols (population parameters μ, σ or p)

Describe in words Type I error (the consequence of rejecting a true null hypothesis.)

Describe in words Type II error (the consequence of failing to reject a false null hypothesis.)

A large restaurant is being sued for age discrimination because 15% of newly hired candidates are between the ages of 30 years and 50 years when 50% of all applicants were in that age bracket. You plan to use hypothesis testing to determine whether there is significant evidence that the company's hiring practices are discriminatory. Part A: State the null and alternative hypotheses for the significance test. (2 points) Part B: In the context of the problem, what would a...

A sample survey asked a random sample of 1498 adult Canadians, “Do you agree or disagree that all firearms should be registered?” Of the 1498 people in the sample, 1282 answered either “Agree strongly” or “Agree somewhat.” Assuming this survey can be considered an SRS of all adult Canadians, what is the proportion of all Canadians who agree (as described) that all firearms should be registered? Your solution must include the following parts, in order. Point form is fine. a)...

The distribution of blood cholesterol level in the population of all male patients 20–34 years of age tested in a large hospital over a 10-year period is close to Normal with standard deviation σ = 48 mg/dL (milligrams per deciliter). At your clinic, you measure the blood cholesterol of 14 male patients in that age range. The mean level for these 14 patients is x̄ = 180 mg/dL. Assume that σ is the same as in the general male hospital...

All euro (common currency in Europe) coins have a national image on the “heads” side and a common design on the“tails” side. Spinning a coin, unlike tossing it, may not give heads and tails equal probabilities. Polish students spun the Belgian euro 280 times, with its portly king, Albert, displayed on the heads side. The result was 153 heads. At a 10% significance level, does this demonstrate that the chances of "heads" when spinning a Belgian euro are different from...

Some dietitians have suggested that highly acidic diets can have an adverse affect on bone density in humans. Alkaline diets have been marketed to avoid or counteract this effect. Veterinary researchers wondered if the same thing true for cats, and whether an alkaline diet might be beneficial. Two groups of 4 cats each were fed diets for 12 months that differed only in acidifying or alkalinizing properties. The bone mineral density (g/cm2) of each cat was measured at the end...

Astronomers have recently discovered an unknown distant galaxy and noticed something abnormal. Specifically, they suspect the percentage of stars that host planets in this galaxy is lower than is typical. (It is known that around 75% of stars throughout the universe have planets). Given the current state of technology, astronomers are not able to conduct a complete scan of all the stars in this galaxy. So instead they randomly observed 45 stars within the new galaxy, and found only 24...
