Q:
# A consumer report counted 72 low quality, 112 medium quality, and 711 high quality computers based on a random sample. The report went on to say that all computers, regardless of quality, are packaged identically and sold at the same price. Use the observed frequencies to create a probability model for the quality of the next computer purchased

Accepted Solution

A:

Total number of computers in sample = 72 + 112 + 711 = 895.

P(LQ) = 72/895 = 0.08

P(MQ) = 112/895 = 0.125

P(HQ) = 711/895 = 0.794

P(LQ) = 72/895 = 0.08

P(MQ) = 112/895 = 0.125

P(HQ) = 711/895 = 0.794
