Please show me the detailed solution.

An electronics manufacturer produces power supply units for digital electronics. A cus- tomer has specified a lower specification limit of 4.9 V and an upper specification limit of 5.1 V for the output voltage of the power supply unit. The manufacturer of the power supply units has calibrated the process to produce units that output 5V on average with a standard deviation of 0.05 V. Assume that the output voltages of the power supply units are normally distributed. The manufacturer supplies 10,000 power supply units to the cus- tomer. A power supply unit is considered defective if it does not satisfy the specification limits. (a) What is the defect ratio of the population of 10,000 units? (b) The customer tests a random sample of 10 power supply units. What random variable best describes the number of defective units found in the sample of 10 units? Explain your answer. (c) What is the probability customer finds one or more defective units in the sample of 10 units? (d) Unknown to the manufacturer, the production process has malfunctioned shifting the mean output voltage to 5.05 V. What is the defect ratio of the population produced by the malfunctioning process? What is the probability that the customer will find one or more defective units in the random sample of 10 units
