A fashion designer wants to know how many new dresses women buy each year. A sample of 271 women was taken to study their purchasing habits. Construct the 90% confidence interval for the mean number of dresses purchased each year if the sample mean was found to be 8.2. Assume that the population standard deviation is 1.1. Round your answers to one decimal place.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
