a. What is the probability that the sample mean is within $500 of the population mean if a sample of size 60 is used (to 4 decimals)? b. What is the probability that the sample mean is within $500 of the population mean if a sample of size 120 is used (to 4 decimals)? In the EAI sampling problem, the population mean is $51,800 and the population standard deviation is $4,000. When the sample size is n-30, there is a...

Would you agree to the statement on random sampling methods. Please explain why. In probability samples “each population element has a known (non-zero) chance of being chosen for the sample.” (StatTrek 2020). Some examples of probability samples are, simple random sampling, stratified sampling, cluster sampling, multistage sampling, and systematic random sampling. Simple random sampling is the population and sample consists of “N” objects, and an example is when people play the lottery. Stratified sampling is based on some type of...

A botanist has developed a new hybrid cotton plant that can withstand insects better than other cotton plants. However, there is some concern about the germination of seeds from the new plant. To estimate the probability that a seed from the new plant will germinate, a random sample of 3000 seeds was planted in warm, moist soil. Of these seeds, 2440 germinated. (a) Use relative frequencies to estimate the probability that a seed will germinate. What is your estimate? (Enter...
