3. Do one of the following, as appropriate: (a) Find the critical value za/2, (b) find the critical
value ta/2, (c) state that neither the normal nor the t distribution applies.

91%; n = 45; o is known; population appears to be very skewed.
O za/2 = 1.75
0 za/2 = 1.70
Neither the normal nor the t distribution applies.

O ta/2 = 1.34

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

step-by-step explanation:

it should be a.

hope it

2+2 obliviously is 4.
