Answer 1

The percentage of attendees who will not buy popcorn is 82.5%.

Explanation:

Total number of attendees at the showing is n = 160 .

Number of attendees who will buy popcorn is, X = 28.

Proportion of attendees who will buy popcorn is:

`p=(X)/(n) \\=(28)/(160)\\ =0.175`

The proportion of attendees who will not buy popcorn is:

`q=1-p\\=1-0.175\\=0.825`

The percentage of attendees who will not buy popcorn is:
`0.825*100 = 82.5\%`

Thus, the percentage of attendees who will not buy popcorn is 82.5%.
