A binomial experiment is given. Decide whether you can use the normal distribution to approximate the binomial distribution. If you can, find the mean and standard deviation. If you cannot, explain why. A survey of adults found that 67% have used a multivitamin in the past 12 months. You randomly select 40 adults and ask them if they have used a multivitamin in the past 12 months. Select the correct answer below and, if necessary, fill in the answer boxes within your choice. O A. No, because nq <5. O B. No, because np <5. O C. Yes, the mean is and the standard deviation is (Round to two decimal places as needed.)

Find the range, the standard deviation, and the variance for the given sample. Round non-integer results to the nearest tenth. 6, 9, 10, 14, 16, 41 range       standard deviation       variance

A binomial experiment is given. Decide whether you can use the normal distribution to approximate the binomial distribution. If you​ can, find the mean and standard deviation. If you​ cannot, explain why.   A survey of adults found that 61​% have used a multivitamin in the past 12 months. You randomly select 50 adults and ask them if they have used a multivitamin in the past 12 months.

QUEST A set of final examination grades in a calculus course was found to be normally distributed with a mean of 69 and a standard deviation of 9. The top 15% of the students taking the test scored will receive a grade of B. What is the cur score?

Use the magnitudes​ (Richter scale) of the 120 earthquakes listed in the accompanying data table. Use technology to find the​ range, variance, and standard deviation. If another​ value, 8.00, is added to those listed in the data​ set, do the measures of variation change much? 3.272.452.542.432.752.372.192.421.911.432.851.731.992.322.332.704.742.873.382.722.833.423.952.993.873.473.082.942.703.602.842.373.033.232.593.643.242.662.352.432.813.952.522.922.983.412.272.562.933.162.201.151.934.002.542.832.352.311.522.801.951.602.452.332.081.553.201.491.812.551.662.352.452.082.192.752.002.792.392.671.692.881.841.991.862.561.972.183.671.553.162.461.881.502.793.283.822.752.452.712.541.642.183.032.361.481.922.322.651.411.391.802.242.302.481.732.402.442.482.44

The ages (in years) of a random sample of shoppers at a gaming store are shown. Determine the range, mean, variance, and standard deviation of the sample data set. 12, 21, 23, 15, 20, 18, 21, 16, 15, 16 The range is 11. (Simplify your answer.) The mean is 17.7. (Simplify your answer. Round to the nearest tenth as needed.) The variance is 12.0. (Simplify your answer. Round to the nearest tenth as needed.) The standard deviation is (Simplify your answer. Round to the nearest tenth as needed.)
