How does the pitch when striding of Aquarius remigis, the common water strider, vary with sexual maturity? Suppose thatresearchers interested in this question collected three simple random samples of ten water striders each, one sample for each levelof sexual maturity, and measured each strider's degree of pitch when striding.For each maturity level, the table provides the mean, x, and standard deviation, s, for the pitch measurements collected alongwith each sample size, n.MaturitySLevelNewborn10.304.2210Juvenile8.325.2810Adult7.473.7810Use software to run a one-way analysis of variance, ANOVA. Report the ANOVA F-statistic to two decimal places.F =Report the P-value of your F-statistic to three decimal places.

The brain volumes (cm³) of 20 brains have a mean of 1113.7 cm³ and a standard deviation of 128.9 cm³. Use the give standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1361.5 cm³ be significantly high? 3 Significantly low values are cm³ or lower. (Type an integer or a decimal. Do not round.)

The salaries of professional baseball players are heavily skewed right with a mean of $3.2 million and a standard deviation of $2 million. The salaries of professional football players are also heavily skewed right with a mean of $1.9 million and a standard deviation of $1.5 million. A random sample of 40 baseball players’ salaries and 35 football players’ salaries is selected. The mean salary is determined for both samples. Let represent the difference in the mean salaries for baseball and football players. Which of the following represents the shape of the sampling distribution for ? skewed right since the populations are both right skewed skewed right since the differences in salaries cannot be negative approximately Normal since both sample sizes are greater than 30 approximately Normal since the sum of the sample sizes is greater than 30
