whats an example of hypothesis testing in real life.

In many ways, hypothesis testing can be compared to a trial in court. What is the equivalent of p-value?

Find the remainder in the Taylor series centered at the point a for the following function. Then show that lim |Rn(x)=0 f(x)=ex f(x) = e a=0 n-∞ First find a formula for f (n) (x). f(n) (x) = (Type an exact answer.) Next, write the formula for the remainder. n+1 Rn(x) = (n+1)! for some value c between x and 0 = 0 for all x in the interval of convergence. (Type exact answers.) Find a bound for Rn(x) that does not depend on c, and thus holds for all n. Choose the correct answer below. ex elx OC. R(x)(n+1 OE. Rn(x)(n+1) | Rn (x)| = (n+1)* = 0 for all x in the interval of convergence by taking the limit of the bound from above and using limit rules. Choose the correct reasoning below. Show that lim R,(x)=0 OA. Use the fact that lim U = 0 for all x to obtain lim |R,(x)| = el*1.0=0. OB. Use the fact that lim = 0 for all x to obtain lim |R,(x)=1+0=0. OC. Use the fact that lim A(+1) (n+1)! = 0 for all x to obtain lim R₁(x) =+0=0. e OD. Use the fact that lim = 0 for all x to obtain fim R₁(x)| =…

Consider the following parametric equations, x=-4t, y=-7t+ 13; -10 sts 10. Complete parts (a) through (d) below. a. Make a brief table of values of t, x, and y t x(t) y(t) 10 -6 0 6 10 (Type integers or decimals.) ○ A. b. Plot the (x, y) pairs in the table and the complete parametric curve, indicating the positive orientation (the direction of increasing t). 130 G c. Eliminate the parameter to obtain an equation in x and y. d. Describe the curve. OA. A line segment falls from left to right as t increases OB. A line segment falls from right to left as t increases OC. A line segment rises from right to left as t increases OD. A line segment rises from left to right as t increases
