2.) Suppose 1000 coins are tossed. Use the normal curve approximation to the binomial distribution to find the probability of getting the following result. Exactly 510 Use the table of areas under the standard normal curve. Clickv here to view page 1. Click here to view page 2. Click here to view page 3. The probability of getting exactly 510 head is (Round to four places as needed)

The standard deviation of the given the data (14, 13, 16, 9, 3} is ♦ If the average American male is 5'10" and the standard deviation is 3", then Yao Ming who is 7'6" is within ◆ standard deviations of the mean? An outlier is an extreme value that is significantly less or more than the rest of the data. In the data below take out the outlier, then calculate using a statistics calculator or spreadsheet, the standard deviation of the heights of 15 soda cans. {92.8, 92.8, 92.9, 92.9, 92.9, 92.8, 92.7, 92.9, 92.1, 92.7, 92.8, 92.9, 92.9, 92.7, 92.8} Round to the nearest 100th. Answer:

State whether you would expect this distribution to be symmetric, left-skewed, orright-skewed, and briefly explain: ages of people obtaining a driver’s license for the firsttime.

Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Find the probability that a given score is less than -0.74 and draw a ketch of the region. Sketch the region. Choose the correct graph below. VA. O B. C. O D. -0.74 -0.74 0.74 -0.74 0.74 The probability is (Round to four decimal places as needed.) of

The average number of cavities that thirty-year-old Americans have had in their lifetimes is 8.  Do twenty-year-olds have a different number of cavities? The data show the results of a survey of 13 twenty-year-olds who were asked how many cavities they have had. Assume that the distribution of the population is normal. 11, 7, 6, 12, 8, 9, 10, 11, 10, 6, 8, 10, 10 What can be concluded at the αα = 0.10 level of significance? The null and alternative hypotheses would be: Please provide number      H0:H0: mean =  __?__  H1:H1:  mean not equal to  __?__   The test statistic t =  __?__(please show your answer to 3 decimal places.) The p-value = __?__ (Please show your answer to 4 decimal places.)
