Answer:
(1) 0.3108
(2) 0.5223
Step-by-step explanation:
The information provided is:
Mean = <em>p</em> = 0.22
Standard Deviation = 0.025
<em>n</em> = 503
Compute the probability that the sample proportion is within ±0.01 of the population proportion as follows:
*Use a <em>z</em>-table.
Thus, the probability that the sample proportion is within ±0.01 of the population proportion is 0.3108.
The new sample size is, <em>n</em> = 903.
Compute the standard deviation as follows:
Compute the probability that the sample proportion is within ±.01 of the population proportion as follows:
Thus, the probability that the sample proportion is within ±.01 of the population proportion is 0.5223.
