Find the INTEGER minimum sample size required to estimate the population proportion p: Margin of error: 0.04; confidence level: 92%; p and a are not known. Answer:
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Answer:
Find the INTEGER minimum sample size required to estimate the population proportion p:
Margin of error: 0.09; confidence level: 95%; from a prior study, p is known to be 33%.
Answer:
Find the INTEGER minimum sample size required to estimate the population proportion p:
in a certain population, body weights are normally distributed with a mean of 152 pounds and a standard deviation of 26
pounds. How many people must be surveyed if we want to estimate the percentage p who weigh more than 180
pounds? Assume that we want 97.5% confidence that the error is no more than 1.7 percentage points; no prior results on
estimating p are available.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff4a16e57-b19a-4e8c-8ca5-66b87701a53a%2F4263e534-fdfc-413c-9d83-38f2ea7ef5ba%2Ff45gp0l_processed.jpeg&w=3840&q=75)
