A process produces strings of Christmas tree lights that historically have experienced a defective rate of 6%. A customer has placed an order for 150 strings of lights. Use the normal approximationKto the binomial distribution to answer parts a through e.a. Calculate the mean and standard deviation for this distribution.The mean is 9.(Round to four decimal places as needed.)The standard deviation is 2.9086.(Round to four decimal places as needed.)b. What is the probability that fewer than 4 strings in this order will be defective?The probability is 0.(Round to four decimal places as needed.)View an example Get more help -ㅁㅁ F3000DOD F4|| FOF5F6F7www▶11F8F9F10Clear allJF11Check answerمسألF12

Suppose baby kittens' weights are normally distributed with a mean of 11.4 and a standard deviation of 2.1. The Z-score tells you how many units above the average (if Z-score is positive) or below the average (if Z- Score is negative) any particular baby kitten's weight is. Find the baby kitten weight that corresponds to the following Z-scores. Use the formula Z where u is the mean, o is the standard deviation, and X is the baby kitten weight. a. Z = = 0.07, X = b.
