Step 3(b) What is the probability that for each firm the sample mean x will be within £25 of the populationmean μ?Let x be the sample mean number of inventory items. To be within 25 items of the mean, u, we want valuesof x to be between a lower value of x = μ-and an upper value of x = μ +Therefore, the desired probability that a sample mean of 60 items is within 25 of the population mean iswhich of the following:P(x - 25 ≤ x ≤ x + 25)P(μ-50 ≤ ≤ μ + 50)P(x - 50 ≤ x ≤ x + 50)P(μ-25 ≤ ≤ μ+25)Submit Skip (you cannot come back)

Please help me in the following question.
B Choosing a topic Sk.. For data that is not normally distributed we can't use z-scores. However, there is an equation that works on any distribution. It's called Chebyshev's formula. The formula 1 where p is the minimum percentage of scores that fall within k k2 is p = 1 - standard deviations on both sides of the mean. Use this formula to answer the following questions. a) If you have scores and you don't know if they are normally distributed, find the minimum percentage of scores that fall within 2.2 standard deviations on both sides of the mean? b) If you have scores that are normally distributed, find the percentage of scores that fall within 2.2 standard deviations on both sides of the mean? c) If you have scores and you don't know if they are normally distributed, how many standard deviations on both sides of the mean do we need to go to have 64 percent of the scores? Note: To answer part c you will need to solve the equation for k.
