7. Circus

A traveling circus has found that its average attendance per performance is 6000 people with a

standard deviation of 1500. Assume that attendance is normally distributed.

a)

Suppose that a town asks the circus to come, but the only available site in town holds a

maximum of 8000 people. What is the probability that this site will reach capacity?

b)

If the circus loses money on 20% of its performances, what attendance must it have to

break even for a performance?

The average daily attendance of a small amusement park is 4,219 people. In order to increase the average daily attendance, the park owners decided to lower the price for admissions. For the first 25 days after the highly publicized price reduction the average daily attendance was 4,537. You can assume that the population standard deviation is 674. Assume that these 25 days can be considered a random sample of the days to come and that daily attendance follows a normal...

A manufacturing company claims that its machines dispense, on average, 7 ounces per cup with a standard deviation of 0.15 ounces. A consumer is skeptical of this claim, believing that the mean amount dispensed is less than 7 ounces. A sample of size 100 is chosen, which yields the average amount per cup: 6.6 ounces, what conclusions can be drawn? State the null and alternative hypotheses, and compute the P–value to justify your answer.
