a randomly selected sample of 50 students spent on average an amount $36 on a date with a standard deviation of $5, what is the standard error of the sample mean?
Solution :
Given that,
mean =
= $36
standard deviation =
=$5
n = 50
The sampling distribution of mean and standard error is ,
= $36
=
/
n = 5 /
50 = 0.7071
The standard error of the sample mean = 0.7071

A sample of 36 randomly selected students has a mean test score of 83.4 with a standard deviation of 8.92. Assume the population has a normal distribution. Find the margin of error, and then find the 95% confidence interval for the population mean.
1. To determine the average number of hours spent studying by college students per week, a sample of 39 students was randomly selected, and found to spend an average of 17.1 hours per week, with a standard deviation of 4.3 hours. Find the 90% confidence interval for the mean number of hours spent studying per week by all college students. What is the upper and lower bound? 2. If I asked a random student how many hours they study per...

The mean score on a science assessment test for 49 randomly selected male high school students was 153. Assume the population standard deviation is 36. The mean score on the same test for 50 randomly selected female high school students was 147. Assume the population standard deviation is 34. At a= 0.05, can you support the claim that the mean score on the science assessment test for male high school students is greater than the mean score for female high...
