I need the excel formulas for these
questions:
The amount of tea leaves in a can from a production line is
normally distributed with μ = 110 grams and σ = 25 grams. A sample
of 25 cans is to be selected. What is the probability that the
sample mean will be between 100 and 120 grams?
The amount of tea leaves in a can from a production line is
normally distributed with m = 110 grams and s = 25 grams. A sample
of 25 cans is to be selected. What is the probability that the
sample mean will be less than 105 grams?
The amount of tea leaves in a can from a production line is
normally distributed with m = 110 grams and s = 25 grams. A sample

sample mean will be greater than 105 grams?
The amount of tea leaves in a can from a production line is
normally distributed with m = 110 grams and s = 25 grams. A sample
of 25 cans is to be selected. So, 95% of all sample means will be
greater than how many grams?
The amount of tea leaves in a can from a production line is
normally distributed with m = 110 grams and s = 25 grams. A sample
of 25 cans is to be selected. So, the middle 70% of all sample
means will fall between what two values?
