Suppose you calculate a z-score of -2.2 and the distribution is normal. Then which of the following is a correct interpretation?   Group of answer choices None of the above are justified interpretations   The observation is about 2.2 standard deviations less than the mean. This means it is less than all but roughly 2.5% of the observations.   The observation is about 2.2 times the variance less than the mean. This means it is less than all but roughly 5% of the observations   The observation is about 2.2 times the variance less than the mean. This means it is less than all but roughly 2.5% of the observations.   The observation is about 2.2 standard deviations less than the mean. This means it is less than all but roughly 5% of the observations.

Mathematics scores on the CBBC standardized exam are normally distributed with a population mean of 164 and a population standard deviation of 12. Ms. Norbury believes her two classes of a total of 48 students have a mathematics comprehension different than 164 and she decides to give her classes the exam. The mean on the exam was 161. Test to determine if her class' mathematics comprehension is different than 164 at the 0.05 level of significance. (Show all seven steps.)

We would like to investigate if there is a difference in mean coffee consumption frequency between students at Rutgers, Princeton, and the University of Michigan. What test would we likely conduct? Independent samples t-test One Sample z-test Paired samples t-test One Way ANOVA

Please answer the second question. Thank you.

Consider the following data: −10, −10, 0, 3, −10, 3, 3  Step 1 of 3: Calculate the value of the sample Variance. Round your answer to one decimal place. Step 2 of 3: Calculate the value of the sample deviation. Round your answer to one decimal place. Step 3 of 3: Calculate the value of the range.
