J 2 for a data set of weights (pounds) And Highway fuel consumption amounts mpg of four types of automobile, the linear correlation coefficient is found in the P value is 0.009. Write a statement that interprets the P value and includes a conclusion about linear correlation. The P value indicates that the probability of a Lydia correlation coefficient that is at least as extreme is (answer)% which is (high/low) so there (is not/ is) sufficient evidence to conclude that there's a linear correlation between weight and highway fuel consumption and automobiles.

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. The table shows the result of the experiment. The researchers will use a chi-square test for homogeneity to analyze the findings. Hatching status Yes No Total Cold 16 11 27 Water Temperature Neutral Hot 38 75 18 56 104 Total 129 58 187 Which of the following is false? All of the conditions are met for conducting a chi- square test for homogeneity. The data came from 3 groups in a randomized experiment. All expected counts are at least 5. The 10% condition is met. The 10% condition is not needed because the eggs were not randomly selected from the population. Incorrect

A baseball team claims that the mean length of its games is more than 1.4 hours. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is not 1.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≠1.4." B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at least 1.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≥1.4." C. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 1.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≤1.4." D. The null hypothesis expressed in words is, "the mean length of a…
