3. during spring 2016, 90 randomly selected purdue undergraduates were asked if, in a typical day, they watch something on an actual television set. a similar survey of 68 purdue staff members was also conducted. the results are recorded in the purdue tv watchers dataset. use minitab to compute a 99% confidence interval based on these samples for the difference between the proportion of undergraduates and staff members who watch something on a tv set in a typical day and give an interpretation of your interval. in particular, are we 99% confident that a higher percentage of staff members watch a tv on a typical day than undergrads

step-by-step explanation:

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
