Which of the following is not true? Choose the correct answer below. A. The area in any normal distribution bounded by some score x is the same as the area bounded by the equivalent z-score in the standard normal distribution. B. A z-score is a conversion that standardizes any value from a normal distribution to a standard normal distribution. C. A z-score is an area under the normal curve. D. If values are converted to standard z-scores, then procedures for working with all normal distributions are the same as those for the standard normal distribution.

A. The area in any normal distribution bounded by some score x is the same as the area bounded by the equivalent z-score in the standard normal distribution - false

B. A z-score is a conversion that standardizes any value from a normal distribution to a standard normal distribution - True

Step-by-step explanation:

A. The area in any normal distribution bounded by some score x is the same as the area bounded by the equivalent z-score in the standard normal distribution- This statement is false in the sense that it is a point that is equivalent to corresponding point of normal distribution.

B. A z-score is a conversion that standardizes any value from a normal distribution to a standard normal distribution.  - This statement is true in the sense that z-score is in the normal standard distribution.

C. A z-score is an area under the normal curve - This statement is true in the sense that z-score is a conversion that standardizes any value from a normal distribution to a standard normal distribution.

D. If values are converted to standard z-scores, then procedures for working with all normal distributions are the same as those for the standard normal distribution - This statement is absolutely true

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
