Python eggs How is the hatching of water python eggs influenced by the temperature of

the snake’s nest? Researchers randomly assigned newly laid eggs to one of three water

temperatures: hot, neutral, or cold. Hot duplicates the extra warmth provided by the

mother python, and cold duplicates the absence of the mother. Here are segmented bar graphs showing the results of the experiment. Describe what you see.

Short Answer

Expert verified

The frequency of hatched eggs is the greatest in hot water, followed by neutral water and cold water.

Step by step solution

01

Given information

We have been given a graph which gives us the relative frequency of hatched eggs to unhatched eggs in cold water, neutral water and hot water.

02

Explanation

It can be inferred from the graph that the relative frequency of hatched eggs to unhatched eggs is 0.7in the case of hot water, between 0.7and 0.6in case of neutral water, and 0.6in case of cold water. Thus, the decreasing order of the relative frequency of hatched to unhatched eggs in the three temperatures of water is: hot water, neutral water, and cold water.

No chi-square The principal in Exercise 7 also asked the random sample of students to record whether they did all of the homework that was assigned on each of the five school days that week. Here are the data:

Last python Refer to Exercises 28 and 30.

a. Verify that the conditions for inference are met.

b. Use Table C to find the P-value. Then use your calculator’s χ2 cdf command.

c. Interpret the P-value from the calculator.

d. What conclusion would you draw using α=0.10?

Munching Froot Loops Kellogg’s Froot Loops cereal comes in six colors:

orange, yellow, purple, red, blue, and green. Charise randomly selected 120 loops and noted the color of each. Here are her data:

Do these data provide convincing evidence at the 5% significance level that Kellogg’s Froot Loops do not contain an equal proportion of each color?

Recent revenue shortfalls in a midwestern state led to a reduction in the state budget for higher education. To offset the reduction, the largest state university proposed a 25%tuition increase. It was determined that such an increase was needed simply to compensate for the lost support from the state. Separate random samples of 50freshmen, 50sophomores, 50juniors, and 50seniors from the university were asked whether they were strongly opposed to the increase, given that it was the minimum increase necessary to maintain the university's budget at current levels. Here are the results:

Which null hypothesis would be appropriate for performing a chi-square test?

a. The closer students get to graduation, the less likely they are to be opposed to tuition increases.

b. The mean number of students who are strongly opposed is the same for each of the 4years.

c. The distribution of student opinion about the proposed tuition increase is the same for each of the 4years at this university.

d. Year in school and student opinion about the tuition increase are independent in the sample.

e. There is an association between year in school and opinion about the tuition increase at this university.
