Ch 8 FRQ ( The distribution of average speeds of the top 53 drivers in NASCAR is roughly symmetric, unimodal, and bell-shaped, with a mean of 184.8 mph and a standard deviation of 7.2 mph. In the space above, draw a Normal Curve, from z=-3 to z=+3. Draw vertical lines at the mean and each whole number standard deviation above and below the mean. Write two rows of numbers under the base line; one row with the number of standard deviations above and below the mean (z-scores), and a row under that with the actual values for this problem. ] What percent of drivers would you expect to have speeds below 199.2 mph ? Show all work. s] What is the area under the curve to the left of a speed of 170.4mph Show all work. What is the probability that a driver selected at random will have a speed below 172.0 mph ? Show all work. B] What percent of drivers would you expect to have a speed above 177.0 mph ? Show all work. How many drivers would you expect to have speeds between 170.4 mph and 177.0 mph…

A survey organization, as part of the United States Census Bureau, conducts a yearly census similar to the one taken every ten years, but with a smaller percentage of participants. One of these surveys estimates with 90% confidence that the mean household income in the U.S. falls between $69,700 and $69,908. Find the point estimate for mean U.S. household income. (Enter your answer as a whole number.) x = Find the error bound for mean U.S. household income. (Enter your answer as a whole number.) EBM =
A political newspaper, Politically Sound, is interested in the distances voters in Rising Falls County live from their nearest polling station. Politically Sound has hired you to estimate the population mean of all such distances for voters in this county. To estimate this population mean, you select a random sample of 17 Rising Falls County voters and record the distance (in km) each voter lives from their nearest polling station. Assume the population is approximately normally distributed. Based on your sample, follow the steps below to construct a 99% confidence interval for the population mean of all the distances voters in Rising Falls County live from their nearest polling station. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results for your random sample. Take Sample Number of voters 17 Sample mean 4.757 Sample standard deviation 2.363 Enter the values of the sample size, the point estimate of the mean, the sample standard deviation, and the…

For the residents in 2014, use R to calculate the interval with 99% certainty that the interval contains the actual population mean of the residents by census tracts. Type in the interval with keyboard. We also know that in each year, the number of residents by census tract in the State of Maryland follows a normal distribution, and the variance in the number of residents within the State of Maryland is the same for different years.

A Biomedical engineer is measuring how much current is needed to stimulate the nerve of a rat to create a muscle function. He is measuring 5 rats and wants to evaluate if less current is needed to stimulate a young animal compared to an old animal. The mean of the current to stimulate young animals is 4.6mA. Meuasrements from trials on Old Rats: 6, 6, 12, 7, 8 (in mA) Can the engineer conclude that old rats need more current?
Can someone please help? Thank you.
Use the Central Limit Theorem to find the mean and standard error of the mean of the sampling distribution. Then sketch a graph of the sampling distribution. The mean price of photo printers on a website is $227 with a standard deviation of $69. Random samples of size 31 are drawn from this population and the mean of each sample is determined. The mean of the distribution of sample means is nothing.
The Z-score tells you the number of standard deviations away from the mean (and in what direction) a data value is. The formula: Z = *- can be used to find the Z-score for a single member of the population. Notice X - μ tells you the signed distance the data value (X) is from the mean. When you divide that by the size of each chunk (the standard deviation) you are measuring the distance in units of the size of the standard deviations (how many standard deviations fit in the distance between the data value and the mean) - which gives you the Z-score. The formula X = μ+Z.o can be used to find the value in the population when given the Z-score (signed number of standard deviations). Notice that Z. tells you how far from the mean the data value is (since Z is the number of standard deviations and is the size of each standard deviation the product tells the total distance). So adding the distance from the mean to the mean gives the location along the number line for the data value. A…
