It is desired to test h0: μ = 55 against h1: μ < 55 using α = 0.10. the population in question is normally distributed with a standard deviation of 20. a random sample of 64 will be drawn from this population. if μ is really equal to 50, what is the probability that the hypothesis test would lead the investigator to commit a type ii error?

the answer is d on edge

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
