Use the above picture to anwer these questions. If we count off 2.5% of the dots in the LEFT tail, above what number on the number line will that dot be located? If we count off 2.5% of the dots in the RIGHT tail, above what number on the number line will that dot be located? Using the 95% Rule, estimate the standard error. Round your answer to four decimal places as necessary. (Hint: It is NOT the standard deviation given in the picture. That represents the standard deviation of just the dots in the picture. The standard error would be the standard deviation of the dots in the picture if it included every possible bootstrap sample. But that picture would contain 10,000,000,000 dots
Suppose that a random sample of adult males has a sample mean heart mass of x¯=310.1 grams, with a sample standard deviation of s=6.6 grams. Since adult male heart masses are generally symmetric and bell-shaped, we can apply the Empirical Rule. Between what two masses do approximately 68% of the data occur? Round your answer to the nearest tenth. Approximately $68\%$68% of the men's heart masses are between _____ grams and ______ grams.
