Computer hard drives must rotate in a balanced way and away from level is called pitch.Samples are taken regularly from production and each disk in the sample is placed in test equipment that results in a pitch measurement. From various samples it is concluded that the population is normal. The variance = image 1 when the process is in control. A sample of 10 is collected each week. The process will be declared out of control if the sample variance exceeds 0.122 What is the probability that it is declared out of control even when variance = image 1?

The height of women ages 20-29 is normally distributed, with a mean of 64.8 inches. Assume o = 2.4 inches. Are you more likely to randomly select 1 woman with a height less than 65.7 inches or are you more likely to select a sample of 19 women with a mean height less than 65.7 inches? Explain. What is the probability of randomly selecting 1 woman with a height less than 65.7 inches? (Round to four decimal places as needed.) What is the probability of selecting a sample of 19 women with a mean height less than 65.7 inches? (Round to four decimal places as needed.) mean height less Are you more likely to randomly select 1 woman with a height less than 65.7 inches or are you more likely to select a sample of 19 women with than 65.7 inches? Choose the correct answer below.

The proportion P residence in a community recycles traditionally been 70%. Policymaker claims of the unfortunate less than 70% now that one of the recycling centers has been relocated. It's 137 out of a random sample of 205 residence in the community said they recycle, is there enough evidence to support the policy makers claim at the 0.05 level of significance?
