Answer 1

Answer:

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

Step-by-step 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:

$p=\frac{X}{n} \\=\frac{28}{160}\\ =0.175$

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: $0.825\times100 = 82.5\%$

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