You are conducting a study to see how much high school students spend on back to school shopping. You first need to determine how many high schoolers to survey. Based on a study done last school year, you believe the population standard deviation is approximately o = 60.7 dollars. You would like to be 90% confident that your estimate is within 1 dollar(s) of average spending on back to school shopping. How many high school students do you have to sample?
A sample of n = 15 scores has a mean of M = 6. One person with a score of X = 22 is added to the sample. What is the value for the new sample mean?
we want to obtain a sample to estimate a population mean. Based on previous evidence, researchers believe the population standard deviation is approximately 38.7. We would like to be 99% confident that the estimate is within 4 of the true population mean. How large of a sample size is required ?
The mean is 146 and the standard deviation is 35. A score of 41 is how many z-scores below the mean?
Find the z-score when x is 5, mean equals 7, and standard deviation 3.
You want to estimate the mean amount of time Internet users spend on Facebook each month. How many Internet users must be surveyed in order to be 90% confident that your sample mean is within 10 minutes of the population mean? Based on results from a prior survey, assume that the standard deviation of the population of monthly times spent on Facebook is 210 minutes.
In a set of 48 months of data for medical the mean is 15 days and standard deviation of 4.2 how many months fewer than 19.2 days per month reported medical leave ( one standard deviation above the mean?
According to Chebyshev's Teorem, at least what percentage of snake lengths are within K= 2.9 standard deviations of the mean?
The average home in the US is expected to cost $240,000. A random sample of 56 homes sold this month showed average price of $232,000. Assume you have access to this data. We are interested in determining cost if the cost of average home has decreased this month. If the test statistic is -1.66 what is the p-value?
There is a new medication for diabetes, fifteen participants take the medication for fifteen days. The average blood glucose before taking the medication was 155 (population mean). The average blood glucose after taking the medication is 110. The standard deviation for the average glucose after taking the medication is 4.6. You want to evaluate if there is statistical evidence that there is a reduction in the mean glucose after taking the medication for 15 days. You must conduct a t-test. What is the t-statistic?
The mean score for first exam in your first organic chemistry class (section A) was 60, with a standard deviation of 5. Your score on the exam was 70. A. How many standard deviations above the mean is your score?
You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately 79.8. You would like to be 95% confident that your estimate is within 5 of the true population mean. How large of a sample size is required?
