Solve the problem. Round the point estimate to the nearest thousandth.
32 randomly picked people were asked if they rented or owned their own home, 8 said they rented. Obtain a point estimate of the proportion of home owners.
Solution :
Given that,
n = 32
x = 8
Point estimate = sample proportion =
= x / n = 8/32=0.25
