A particular brand of diet margarine was analyzed to determine the level of polyunsaturated fatty acid. A sample of six packages resulted in the following percentage values: 16.8, 17.2, 17.4, 16.9, 16.5, 17.1

a. Check the assumption that the level of polyunsaturated fatty acid is normally distributed.
b. Calculate a 99% confidence interval on the mean μ. Provide a practical interpretation of this interval.
c. Calculate a 99% lower confidence bound on the mean Compare this bound with the lower bound of the two-sided confidence interval and discuss why they are different.

none cuz there are no "following statements" regarding the question

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.
