The heat evolved in calories per gram of a cement mixture is approximately normally distributed. the mean is thought to be 100, and the standard deviation is 2. you wish to test
h0: μ=100
versus
h1: μ≠100
with a sample of n = 9 specimens. a. if the acceptance region is defined as 98.5 ≤
x¯¯¯
≤ 101.5, find the type i error probability α. b. find β for the case in which the true mean heat evolved is 103. c. find β for the case where the true mean heat evolved is 105. this value of β is smaller than the one found in part (b). why?

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

step-by-step explanation:

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
