An SRS of 400 high school seniors gained an average of ¯=21 points in their second attempt at the SAT Mathematics exam. Assume that the change in score has a Normal distribution with standard deviation =48. You can find the critical values to three decimal places by using the last row in table C. (a) Find a 95% confidence interval for the mean change in score in the population of all high school seniors. (Enter your answers rounded to two decimal places.)

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
