The data below represent the weight losses for people on three different exercise programs. if we want to test the claim that the three size categories have the same means, why don't we use three separate hypothesis tests for mu 1=mu 2, mu 2=mu 3, and mu 1=mu 3? exercise a exercise b exercise c 2.5 5.8 4.3 8.8 4.9 6.2 7.3 1.1 5.8 9.8 7.8 8.1 5.1 1.2 7.9 a. a hypothesis test for comparing two means does not exist. b. the risk of type ii error increases and becomes too high. c. the risk of type i error increases and becomes too high. d. actually, we do want to use three separate hypothesis tests.

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

whatvare the choices
