Another similar study is to be undertaken to compare the mean posttest scores for BACC and traditionally taught high school biology students. The objective is to produce a 99% confidence interval for the true difference in the mean posttest scores. If we need to sample an equal number of BACC and traditionally taught students and want the width of the confidence interval to be 1.0, how many observations should be included in each group

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.

the cost function, c(x), is the total cost of manufacturing x units of the product. how many units must the company produce and sell if they wish to make a b. if the company produces and sells 2000 units, would they obtain a profit or loss?

median = 4

step-by-step explanation:

we are given a histogram which shows a data distribution. given that all class widths are 1, we are to find the median of this data distribution.

in any data set or distribution, median is its middle value such that the data is sorted out in an ascending order.

so here, we have 7 values and the middle value will be 4 as it separates the higher half from the lower half of the date distribution.

median = = 4
