Match the term to its definition.
We can eliminate sampling error by selecting an unbiased sample
It is better to try to match the characteristics of the sample to the population rather then relying on randomization
According to the 68-95-99.7 rule what percent of the population are more than 2 standard deviations away from the mean?
According to the 68-95-99.7 rule what percent of the population are between 1 standard deviation below the mean and 2 standard deviations above the mean?
The sampling distribution of the mean becomes approximately normally distributed when which of the following conditions is met?
You select a sample of 100 and find a mean of 60 and a standard deviation of 12. What is the standard error of the sampling distribution of sample means?
What is the Z score where 92% of the normal curve is below that z score and 8% of the normal curve lies above that same z score?
What are the Z values of the limits of the area covering the middle 25% of the area under the normal curve?
The Cheebles cookie factory changed their recipe. The inspectors took a sample of the new cookies and found that the mean weight of the sample was 42 grams with a standard deviation of 4 grams. The Cheebles CEO specifically asked the inspectors to use these statistics to find the lower and upper boundary weights of 50% of their cookies
What are the Z values of the limits of the area covering the middle half of the area under the normal curve that the inspectors would use to find this information for the CEO of Cheebles?
