Answer:
Step-by-step explanation:
Given that in a recent poll 1 of 1000 American adults, the number saying that exercise is an important part of daily life was 753.
Sample proportion = 
To find 90% confidence interval we must find std error of proportion first
As per central limit theorem, sample proportion will follow a normal distribution with mean = 0.753
Std error of proportion= 
90% Z critical value = 1.645
Margin of error = 1.645*0.01363 = 0.0224
Confidence interval lower bound = 0.753-0.0224=0.731
Upper bound = 0.775
Hence, option A 0.64 is the correct answer.
Further explanation:
Ounce is a larger unit than grams. When we have to go from a smaller unit to a larger unit we use division.
So,
Given
28.3 grams = 1 ounce
Then

Hence, option A 0.64 is the correct answer.
