The mean incubation time for a type of fertilized egg kept at a certain temperature is 17 days. Suppose that the incubation fimes are approximately normally distributed with a standard deviation of 2 days. Complete parts (a) through (e) below. B. If 100 fertilized eggs were randomly selected, 48 of them would be expected to hatch between 13 and 17 days. C. If 100 fertilized eggs were randomly selected, exactly would be expected to hatch on day 13 or on day 100 fertilized eggs, 17 eggs would be expected to hatch between 13 and 17 days. (e) Would it be unusual for an egg to hatch in less than 11 days? Why? The probability of an egg hatching in less than 11 days is \( \square \), so it \( \square \) be unusual, since the probability is \( \square \) than 0.05. (Round to four decimal places as needed.)

If a scatter plot shows points that are closely clustered together, what can you infer about the correlation between the variables?

In how many ways can a committee of 5 students be formed from 10 students?

A water bottling facility has a mean bottling rate of 35.2 thousand bottles per hour with a standard deviation of 2.04 thousand bottles, A nearby cola bottling facility has a mean bottling rate of 26.9 thousand bottles per hour with a standard deviation of 1.51 thousand bottles. One Wednesday from noon to \( 1: 00 \) p.m., the water bottling facility bottled 36.9 thousand bottles of water, and the cola bottling facility bottled 27.9 thousand bottles of cola. Which facility increased their efficiency more during that hour? Answer

Four scenarios of statistical studies are given below. Decide which study uses a population parameter. Answer 1000 of the 1883 participants in last year's Ironman in Kona, Hawail were interviewed. \( 68 \% \) of those interviewed said they became interested in triathlons after first ofmpeting in marathons. 351 dog owners who were surveyed, 70 reported owning two dogs. Parkland Hospital performs 15,000 births a year. Of 1000 subjects in a study on multiple births, 38 gave birth to twins. in \( 2001.78 \% \) of children diagnosed with cancer were in remission after five years, and this number is improving.
