A medical experiment compared zinc supplements with a placebo for reducing the duration of colds. Let μ denote the mean decrease, in days, in the duration of a cold. A decrease to μ = 1 is a practically important decrease. The significance level of a test of H0: μ = 0 versus Ha: μ > 0 is defined as a) the probability that the test fails to reject H0 when μ = 1 is true.
b) the probability that the test rejects H0 when μ = 0 is true.
c) the probability that the test rejects H0 when μ = 1 is true.

step-by-step explanation:

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
