Answer #1

Answer:-

Given that:-

The daily high temperature in Winnipeg during the month of January is known to follow a normal distribution with a mean of −20◦C. It is also known that 95% of all daily high temperatures in Winnipeg during the month of January are between −32◦C and −8◦C.

What is the approximate value of σ?

As per Emperical Rule

95% data lies b/w 2 Standard deviation from the mean

Hence,
