Suppose that a shipment of 19 calculators is received by a school. Suppose also that 36% of all calculators have dead batteries. Relevant formulas: μ = np, σ = √√npq, where q = 1 − p. (a) Fill in the values below. n = 0.64 Sorry, your answer is wrong... The number of trials is an integer. Find it in the problem description. p = 6.84 Sorry, your answer is wrong... The probability of "success" should be a decimal number. You might have forgotten to divide by 100? q = 2.09 Sorry ☑ your answer is wrong... Use the formula q = 1-p, where p is the value you just found. (b) What is the mean (or expected value) of the number of calculators received by the school that have dead batteries. Do not round. (c) What is the standard deviation of the number of calculators received by the school that have dead batteries. Round to 2 decimal places.
