Please load the data set into StatCrunch, then answer the following questions, using StatCrunch to help with your computations: Is the distribution of body temperatures normal? Is the true population mean temperature really 98.6 degrees F as is commonly assumed? Is there a significant difference between males and females in normal temperature?

TRUE, this is exactly what we mean by 90% confidence when we are constructing confidence intervals. If you were to take 10 samples from a population and construct a 90% confidence interval for the mean from each one, you would expect 9 of them to cover the true population mean and 1 of them to miss the population mean.

When we have two or more groups (generally 3+), and want to compare them on the mean of a quantitative variable, then we use ANOVA. To do ANOVA in CrunchIt or StatCrunch, select Stat, then ANOVA, then One Way. If the data from your groups are in separate columns, select those columns, and click on Calculate.

(b) Use StatCrunch to determine and a 95% confidence interval for the mean amount of time Americans age 15 or older spend eating and drinking each day. Interpret the interval. (c) Could the interval be used to estimate the mean amount of time a 9-year-old American spends eating and drinking each day?

If 16 men are chosen, find the probability that their mean score is less than 590. Objective 2 – Describe the Distribution of the Sample Mean: Non-Normal Population. If the original population is not normally distributed, then the distribution of the sample means will become approximately normally distributed as n …
