Using the raw data please complete the following:

1.At Suntronic, you are responsible for selecting the manufacturing process that yields intraocular lens with the least variability/variance in terms of optical power (diopters). At this point, you don't know which (if either) process yields samples with a higher variance (hint: pick correct alternate hypothesis). Are you able to select the process with the least variance with 98% confidence?

a. Null Hypothesis

b. Alternate Hypothesis

c. One-tailed or two-tailed?Why?

d. ? value

e. p-value (Show output from all software as appropriate)

f. Is the p-value less than ? value?Explain why.

2. Now assume you know that Fabrication Process 1 should yield samples with less variance in optical power according to the fundamentals of the manufacturing process (hint: pick correct alternate hypothesis).Based on your sampling, are you able to confirm that Fabrication Process 1 has the least variance with 95% confidence?

a. Null Hypothesis

b. Alternate Hypothesis

c. One-tailed or two-tailed?Why?

d. ? value?

e. p-value (Show output from all software as appropriate)

f. Is the p-value less than ? value?Explain why.
