How many tissues should a package of tissues contain? researchers have determined that a person uses an average of 41 tissues during a cold. suppose a random sample of 10,000 people yielded the following data on the number of tissues used during a cold: x = 35, s = 18. identify the null and alternative hypothesis for a test to determine if the mean number of tissues used during a cold is less than 41.

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
