You may need to use the appropriate appendix table or technology to answer this question. A population has a mean of 300 and a standard deviation of 24. A sample of 144 observations will be taken. What is the probability that the sample mean will be between 295 to 305? 0.0124 0.1650 0.8350 0.9876

Step 1
The standard error of the mean (SE) is calculated by dividing the standard deviation (σ) by the square root of the sample size (n). SE = σ / √n In this case, the standard deviation (σ) is 24 and the sample size (n) is 144. SE = 24 / √144 SE = 24 / 12 SE = 2 Show more…

Question 12 A certain standardized test has scores which range from 0 to 500, with decimal scores possible. Scores on the exam are normally distributed with a mean of 306 and a standard deviation of 42. Find the percentile P73 for the scores of students taking the exam. Round your answer to 2 decimal places. Question 13 The mean salary of people living in a certain city is $37,500 with a standard deviation of $2,123. A sample of 39 people is selected at random from those living in the city. Find the probability that the mean income of the sample is within $500 of the population mean. Round your answer to 4 decimal places.

1.A population has a standard deviation of 16. If a sample of size 64 is selected from this population, what is the probability that the sample mean will be within ±2 of the population mean? a. 0.6826 b. 0.3413 c. -0.6826 d. Since the mean is not given, there is no answer to this question 3.A simple random sample of 5 observations from a population containing 400 elements was taken, and the following values were obtained. 12 18 19 20 21 A point estimate of the mean is a. 400 b. 18 c. 20 d. 10
