q1) The normal drive to work is 9.6 miles. Expect the standard deviation is 1.8 miles. On the off chance that an irregular example of 36 utilized individuals who drive to work are chosen, discover the likelihood that the mean of the example miles headed to work is somewhere in the range of 9 and 10 miles

q2) Data aggregated by the National Climatic Data Center shows that the normal breeze speed in miles each hour for St. Louis,Missouri, is 9.7. Assume wind speed estimations are ordinarily conveyed for a given geographic area. On the off chance that 22.45% of the time the breeze speed estimations are more than 11.6 miles each hour, what is the standard deviation of wind speed in St. Louis?
