Amanufacturer of television sets is interested in the effect on tube conductivity of four different types of coating for color picture tubes. a completely randomized experiment is conducted and the following conductivity data are obtained: coating type conductivity 1 143 141 150 146 2 152 149 137 143 3 134 136 132 127 4 129 127 132 129 is there a difference in conductivity due to coating type? use α = 0.05 . estimate the overall mean and the treatment effects. compute a 95 percent confidence interval estimate of the mean of coating type 4. compute a 99 percent confidence interval estimate of the mean difference between coating types 1 and 4. test all pairs of means using the fisher lsd method wit

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
