- State the generic error for an interpolating formula?the SAT is standardized so that the average score on the verbal test is 500 each year. If you select a group of 100 graduating seniors who have taken the verbal SAT, What value would be obtained for their average score?The predicted college GPA for a high school GPA of 3.8 and a college board score of 500 is (Round to the nearest tenth as needed.)
- Would like to know how to solve this with ti-84 calcIn a study at The Ohio State University, 16 student volunteers drank a randomly assigned number of cans of beer. Thirty minutes later, a police officer measured their blood alcohol content (BAC) in grams of alcohol per deciliter of blood. Throughout the United States, the legal BAC limit is 0.08. The students were equally divided between men and women and differed in weight and usual drinking habits. Because of this variation, many students do not believe that the number of ingested drinks predicts BAC well.The data in the given figure consists of: a.2 unpaired sets of values, each of which has 16 values b.32 ordered pairs of values c.16 ordered pairs of valuesA consumer wanted to find out how accurate Siri (an Apple digital assistant) is, so he asked questions on general facts and recorded how many Siri got right.

- A certain county had a population of 34,485 people. The county hospital is interested in estimating the number of people in the county with blood type-O. To do this, they test blood samples from 228 patients. Out of this group, 10 have blood type-O. Use this sample to estimate the number of people in the county with blood type-O.A random sample of 5000 people was conducted to determine whether the proportion of Indiana residents who own an iPhone is the same as the national proportion of 57%. It was determined that out of the 5000 individuals sampled, 2,773 owned an iPhone. Report the p-value of the test to four decimal places.The control department of a light bulb manufacturer randomly picks 4400 light bulbs from the production lot every week. The records show that, when there is no malfunction, the defect rate in the manufacturing process (due to imperfections in the material used) is 1%. When 1.5% or more of the light bulbs in the sample of 4400 are defective, the control unit calls repair technicians for service. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p, where p is the proportion of defective light bulbs in a sample of 4400 when there is no malfunction. (b) Find the standard deviation of p. |(c) Compute an approximation for P(p>0.015 ), which is the probability that the service technicians will be called even though the system is functioning properly.

By taking your temperature , of course. But what temperature should the thermometer show if your're healthy? Is this temperature the same for everyone? Several years ago, researchers conducted a study to determine whether the "accepted" value for normal body temperature, 98.6oF, is accurate. They used an oral thermometer to measure the temperatures of a random sample of healthy men and women aged 18 to 40. As is often the case, the researchers did not provide their original data. Allen Shoemaker, from Calvin College, produced a data set with the same properties as the original temperature readings. His data set consists of one oral temperature reading for each of the 130 randomly chosen, healthy 18- to 40-year-olds. A dotplot of Shoemaker's temperature data is shown below. A vertical line at 98.6oF was added for reference. Exploratory data analysis revealed…
