question 72

Multiple Choice

Discrete Components, Inc.manufactures a line of electrical resistors.Presently, the carbon composition line is producing 100-ohm resistors.The population variance of these resistors "must not exceed 4" to conform to industry standards.Periodically, the quality control inspectors check for conformity by randomly select 10 resistors from the line, and calculating the sample variance.The last sample had a variance of 4.36.Assume that the population is normally distributed.Using $\alpha$ = 0.05, the appropriate decision is _________________.

• A)increase the sample size
• B)reduce the sample size
• C)reject the null hypothesis
• D)fail to reject the null hypothesis
• E)maintain status quo
