Exam 10: Data Description and Probability Distributions

Use the rule-of-thumb test to check whether a normal distribution (with the same mean and standard deviation as the binomial distribution) is a suitable approximation for the binomial distribution with given the properties: -n = 20, p = .8

Construct a frequency table: -The following is the number of hours students studied per week on average. Use five intervals, starting with 0 - 4.

A botanist wants to grow a rare plant in his greenhouse. The probability that a given bulb will mature is 0.42. Suppose 6 bulbs are planted.(A) Write the probability function defining this distribution.(B) What is the probability that 3 or more bulbs will mature?(Round your answer to three decimal places.)

Find the mode for the data set: 2, 11, 35, 2, 9, 35, 11, 9, 7, 2, 2, 2, 2, 9, 2

Assume the distribution is normal. Use the area of the normal curve to answer the question. Round to the nearest whole percent: -The average size of the bass in a lake is 11.4 inches, with a standard deviation of 3.2 inches. Find the probability of catching a bass longer than 17 inches.
