The age of all farmers are normally distributed with a mean 48 years old and standard deviation 12 years old.

Part A
About % of all farmers are older than 16 years old.
(Rounding the percentage to 2 decimal places if possible)

Part B
About % of all farmers are younger than 38 years old.
(Rounding the percentage to 2 decimal places if possible)

Part C
About % of all farmers are between 28 years old and 61 years old.
(Rounding the percentage to 2 decimal places if possible)

Part D
About 4% of all farmers are older than years old.
(Rounding the answer to 3 decimal places if possible)

Part E
About 86% of all farmers are younger than years old.
(Rounding the answer to 3 decimal places if possible)

Part F
About middle 73% of farmers between years old and years old.
(Rounding the answer to 3 decimal places if possible)

Suppose the age is normally distributed with a mean of 62 years old and a standard...

Suppose the age is normally distributed with a mean of 62 years old and a standard deviation of 3.7 years. 1. One of the patient’s age of diagnosis was 1.63 standard deviations above the mean. What was this patient’s age when he was diagnosed? 2.Using Z > 2 as a criterion for an outlier, what is the minimum sample size such that a sample mean of 62.5 years would be classified as an outlier?

Problems 1-4 assume a normally distributed population with a mean = 48 and standard deviation = 5. Be sure to sketch the curve, include formulas & work, round appropriately, and circle your final answer. What percent of the scores fall: at or below 54? at or above 40? (6 points) What proportion of scores lie between: 31 and 48? 31 and 54? (4 points) Suppose we took a sample of 5000 scores from this distribution. Of those 5000 scores, how...
