28) A study published in the American Journal of Public Health was conducted to determine whether the use of seat belts in motor vehicles depends on ethnic status in San Diego County. A sample of 792 children treated for injuries sustained from motor vehicle accidents was obtained, and each child was classified according to (1) ethnic status (Hispanic or non-Hispanic) and (2) seat belt usage (worn or not worn) during the accident. The number of children in each category is given in the table below. Seat belts worn Seat belts not worn Hispanic 31 283 Non-Hispanic 148 330 Referring to these data, which of the following conclusions should be reached if the appropriate ni hypothesis is conducted using an alpha = .05 level?

When making an ice cream sundae, you have a choice of 33 types of ice cream flavors: chocolate (C), vanilla (V), or Moose Tracks (M); a choice of 22 types of sauces: hot fudge (H) or butterscotch (B); and a choice of 22 types of toppings: whipped cream (W) or fruit (F). If you are choosing only one of each, list the sample space in regard to the sundaes (combinations of ice cream flavors, sauces, and toppings) you could pick from. Separate the elements of the sample space with commas.

16. The Higher Education Research Institute at UCLA collected data from 203,967 incoming first-time, full-time freshmen from 270 four-year colleges and universities in the U.S. 71.6% of those students replied that, yes, they believe that same-sex couples should have the right to legal marital status. Suppose that you randomly pick twelve first-time, full-time freshmen from the survey. You are interested in the number that believes that same-sex couples should have the right to legal marital status.What is the standard deviation (?)?

I need help on these questions. The table is attached. Use Table B, starting at line 119, to choose the first 5 drivers in the sample. Drag the token representing the label of the driver selected to the appropriate column. (b) One question asked was, “Recalling the last ten traffic lights you drove through, how many of them were red when you entered the intersections?” Of the 880 respondents, 171 admitted that at least one light had been red. A practical problem with this survey is that people may not give truthful answers. What is the likely direction of the bias: do you think more or fewer than 171 of the 880 respondents really ran a red light? A) Fewer than 171 of the 880 respondents really ran a red light. B) More than 171 of the 880 respondents really ran a red light. Why would there be such a bias? A) The test suffers from sample bias. B) People may be concerned that they will get in trouble if they admit to running red lights. C) Those…
1. A lawn mower company will produce 1,500 lawn mowers by 2020. In an effort to determine how much maintenance free consumers will take when they already buy lawn mowers, the company decided to conduct a study over the past 1 year of these mowers. . First, a random sample was taken by contacting 200 grass mowers. The company owner provides an 800 number and is asked to contact the company when the first repair is needed for the lawn mower. Owners who no longer use lawn mowers to cut their grass are either disqualified or not sampled. After 1 year, it turned out that 187 owners had reported for the first repair. However, the other 50 disqualified themselves. The average number per year until the first improvement was 5.3 times for samples deemed feasible. It is believed that the standard deviation is 1.28 per year. If the company wants to advertise the lawnmower and with a confidence level of 95%, what is the estimated annual mean value of repair-free lawn mower for this lawn mower?…
Management of a company that produces a medical device has carefully selected and screened 220 finished items (packaged, ready to ship). The team agrees that the sample contains 33 defective items, all for various visual defects on the package such as crooked labels, poor seal, errant marks on package, etc. The items are then given to an inspector for classification into “defective” and “non-defective” piles. The inspector ends up rejecting 9 non-defective items, and accepting 11 defective items. The inspector classifies the remaining items in the sample correctly. Find the following (answer as a probability, NOT a percentage. Use 3 decimal places. Notice that alpha = 9/187, Beta = 11/33, and p = 33/220. P(inspector accepts the item and its actually non-defective) =
