In an experiment designed to monitor impedance to leg movement, Korean engineers attached electrodes to the ankles and knees of volunteers. Of interest were the voltage readings between pairs of electrodes. These readings were used to determine the signal-to nose ration (SNR) of impedance changes such as knee flexes and hip extensions.a). Six voltage electrodes were attached to key parts of the ankle. How many electrode pairs on the ankle are possible?b). Ten voltage electrodes were attached to key parts of the knee. How many electrode pairs on the ankle are possible?c). Determine the number of possible electrode pairs such that one electrode is attached to the knee and one is attached to the ankle.

Note: For Exercises 13 through 62 that follow, round the answers to 3 decimal places wherever necessary. In Exercises 13 through 16, add the following signed numbers as indicated. 13. a. +15 + (+8) b. 7 + (+18) + 5 c. 0 + (+25) d. -18 + (-4) + (-11)

A person is interested in assessing the relationship between the average number of cigarettes smoked in a day, X, and systolic blood pressure, Y, among smokers. For this data set, see the photo below that shows data for a sample of 11 individuals. a.) Provide the value of the coefficient of determination and, in a sentence, Provide an interpretation of this value. b.) How much would you expect systolic blood pressure to change if a person commits to reducing their cigarettes consumption by 1 cigarette per day? C.) Do we reject or accept Ho?

The magnitude of earthquakes isnce 1900 that measure 0.1 or higher on the Richter scale in California is approximately normally distributed with u= 6.2 and o= 0.5 according to data obtained from the US geological Survey. Based on this data, geologists can tell us that approximately 20% of all earthquakes in California have magnitudes of ____ or more. Find the missing value in this statement  a) 7.02 b) 6.62 c) 6.96 d) 6.84 e) 6.72

According to a dental association, 68% of all dentists use nitrous oxide (laughing gas) in their practice. In a random sample of 500 dentists, let p represent the proportion who use laughing gas in practice. Complete parts a through d below. a. Find E(p). E (6) (Round to two decimal places as needed.) = b. Find on. p (Round to four decimal places as needed.) c. What does the Central Limit Theorem say about the shape of the sampling distribution of p? O A. The Central Limit Theorem says that as the sample size grows large, the sampling distribution of p will become approximately normal. OB. The Central Limit Theorem says that the shape of the sampling distribution of p is completely determined by the population parameter p. С. The Central Limit Theorem does not say anything about the sampling distribution of p because it is not a population mean. O D. The Central Limit Theorem says that as the sample size grows large, the sampling distribution of p will approach the population…

A person gets on and off a bathroom scale four times. The four readings (in pounds) are 148, 151, 150, and 152. Each time after the person gets off the scale, the reading is 2 lb. a) Is it possible to estimate the uncertainty in these measurements? If so, estimate it. If not, explain why not. b) Is it possible to estimate the bias in these measurements? If so, estimate it. If not, explain why not.

The mean daily maximum temperatures at Komakuk Beach, in the Yukon, were recorded for The month from 1958 to 1990. The data are represented by the formula T=17.11sin(0.60M – 21.83)– 5.38, where Tis the temperature ("C) and Mis the number of the month in the year (1 to 12). a) What is the maximum mean daily temperature? b) What is the minimum mean daily temperature? c) What is the mean daily temperature for May? d) In a typical year, during how many months will the mean daily temperatures be higher than 0°C? Give your answer to the nearest tenth of a month.

Weatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used to classify Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of ? = 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 37 waves showed an average wave height of x = 16.5 feet. Previous studies of severe storms indicate that ? = 3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use ? = 0.01.
