Use the following information: A researcher is interested in examining the difference in the average egg incubation temperature of two lizards in North Carolina, the native green anoles versus the invasive brown anoles. To investigate this, she takes two random samples from both of the lizard populations and calculates the average egg incubation temperature, standard deviation, and sample size for each of the two samples.
The average incubation temperature for the 25 sampled brown anoles is 83.2 degrees F, with a sample standard deviation of 20.2 degrees F. The average incubation temperature the 28 samples green anoles is 80.1 degrees F, with a sample standard deviation of 17.4 degrees F. She has also determined that the two samples do not exhibit strong skewness and appear approximately normal.
A. Determine the appropriate t, critical value for a 99% confidence interval for the difference between the true mean incubation temperatures for the two different anole species, mu1 - mu2.
B. Determine the standard error for the 99% confidence interval for the difference between the true mean incubation temperatures for the two different anole species, mu1 - mu2.

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
