Answer #1

99% confidence interval formla for the mean batting average for professional baseball players is ,

= ( sample mean - margin of error , sample mean + margin of error )

so give are , the sample mean = 283 and Margin of error = 0.051

so ,

=( 283 - 0.051 , 283 + 0.051 )

= ( 282.949 , 283.051 )

so the final answer is the 99% confidence interval for the mean batting average for professional baseball players is ,

= ( 282.949 , 283.051 )

these is the correct answer.
