Find the P-value for the indicated hypothesis test with the given standardized test statistic, \( z \). Decide whether to reject \( \mathrm{H}_{0} \) for the given level of significance \( \alpha \). Right-tailed test with test statistic \( z=1.53 \) and \( \alpha=0.08 \) P-value \( =\square \) (Round to four decimal places as needed.) State your conclusion. Fail to reject \( \mathrm{H}_{0} \) Reject \( \mathrm{H}_{0} \)

How do you identify the relationship between two variables in a scatter plot?

Knowing that \( 99.7 \% \) of all \( z \)-scores are between -3 and +3 , what is the \( P \)-value for \( z=-5.14 \) ? 0.000 0.0514 0.2981

Baseball regression line prediction: Suppose the regression line for the number of runs scored in a season, \( y \), is given by \( \hat{y}=-730+4300 x \), where \( x \) is the team's batting average. a. For a tearn with a batting average of 0.235 , find the expected number of runs scored in a season. Round your answer to the nearest whole number. b. If we can expect the number of runs scored in a scason is 480 , then what is the assumed team's batting average? Round your onswer to three deeima! places.

What is a scatter plot?

With \( P \)-value \( =0.000 \) and \( \alpha=0.05 \), should we reject \( H_{0} \) ? yes no
