Step-by-step explanation:
Hi there! The answer is,<em>6</em><em> </em><em>ounces</em><em> </em><em>of</em><em> </em><em>sports</em><em> </em><em>drink</em><em> </em><em>for</em><em> </em><em>each</em><em> </em><em>player</em><em>.</em> Pay attention to the following steps:
1 quart= 32 ounces
3 quarts= 32×3 =96 ounces
96÷16= 6 ounces
Answer:
Step-by-step explanation:
a)
Number of sample, n = 100
p = 0.78
q = 1 - p = 1 - 0.78
q = 0.22
For a confidence level of 90%, the corresponding z value is 1.645.
The formula for determining the error bound for the proportion is
z × √pq/n
= 1.645 ×√(0.78 × 0.22)/100
= 1.645 × 0.0414 = 0.068
The upper boundary of the population proportion is
0.78 + 0.068 = 0.85
The lower boundary of the population proportion is
0.78 - 0.068 = 0.71
b) For a confidence level of 95%, the corresponding z value is 1.96.
Therefore,
= 1.96 ×√(0.78 × 0.22)/100
= 1.96 × 0.0414 = 0.081
The upper boundary of the population proportion is
0.78 + 0.081 = 0.86
The lower boundary of the population proportion is
0.78 - 0.081 = 0.7
