1. Recall from Example 5.5 that Sound City also sells the ClearTone-400 satellite car radio. For this radio, historical sales records over the last 100 weeks show 6 weeks with no radios sold, 30 weeks with one radio sold, 30 weeks with two radios sold, 20 weeks with three radios sold, 10 weeks with four radios sold, and 4 weeks with five radios sold. Estimate and write out the probability distribution of x, the number of Clear Tone-400 radios sold at Sound City during a week.
2. Use the estimated probability distribution in Exercise 5.8 to calculate m , s2, and s .
3. Use your answers to Exercises 5.8 and 5.9 to calculate the probabilities that x will lie in the intervals [mx ± sx], [mx ± 2sx], and [mx ± 3sx].
