The question is incomplete. The complete question is :
In a poll, 1100 adults in a region were asked about their online vs. in-store clothes shopping. One finding was that 43% of respondents never clothes-shop online. Find and interpret a 95% confidence interval for the proportion of all adults in the region who never clothes-shop online.
Solution :
95% confidence interval for p is :
0.401 < p < 0.459
Therefore, 95% confidence interval is from 0.401 to 0.459
Answer:
1) 147
2) 87
Step-by-step explanation:
1) Area of triangle = × base length × height
= × 14 × 10
= 70
Area of a semicircle = ( r is the radius)
Radius = half of diameter = = 7m
Area of semicircle =
= 77 ( Nearest whole number )
Total area = 77 + 70 = 147
2) Divide the shape into 2 rectangles
Area of a rectangle = length × width
Rectangle 1 = 7 × ( 3+3+5 )
= 7 × 11 = 77
Rectangle 2 = 2 × 5
= 10
Total Area = 77 + 10 = 87
