In a randomized experiment with a random sample of 40 newborn rats, 20 were fed on a high protein diet and 20 on a low protein diet. Their weight gains were measured and summarized in following table. sample size sample mean sample SD High Protein 20 135 18 Low Protein 20 125 15 Use T test to check if diet has an influence on weight gain in newborn rats with significant level 0.05. Please, calculate the T test statistics value, and put the numeric value below (auto grading). (Hint: Use df = +−) Your 15

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
