Researchers fit data from over 6000 fetal ultrasounds. They measured the femur length, L, (in millimeters) as a function of the fetus age, t, (in weeks) and formula below. Calculate the rate of growth, dL at t= 15, 20, and 30 weeks. Does the rate of growth of the fetus increase or decrease as it ages? L= - 37.52 + 3.68t – 6.35 x 10 -43 dL Write a function for dt dL dt (Use integers or decimals for any numbers in the expression.)

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
