A production process manufactures electronic components with timing signals whose duration follows a normal distribution. A random sample of 11 components was taken, and the durations of their timing signals were measured. a. The probability is 0.10 that the sample variance is bigger than what percentage of the population variance? b. The probability is 0.10 that the sample variance is less than what percentage of the population variance? Click the icon to view a table of lower critical values for the chi-square distribution. Click the icon to view a table of upper critical values for the chi-square distribution. FITB a. The probability is 0.10 that the sample variance, expressed as a percentage of the population variance, is greater than or equal to %. (Round to the nearest hundredth as needed.) b. The probability is 0.10 that the sample variance, expressed as a percentage of the population variance, is less than or equal to% (Round to the nearest hundredth as needed.)
