The bank manager wants to show that the new system reduces typical customer waiting times to less than 6 minutes. one way to do this is to demonstrate that the mean of the population of all customer waiting times is less than 6. letting this mean be µ, in this exercise we wish to investigate whether the sample of 95 waiting times provides evidence to support the claim that µ is less than 6. for the sake of argument, we will begin by assuming that µ equals 6, and we will then attempt to use the sample to contradict this assumption in favor of the conclusion that µ is less than 6. recall that the mean of the sample of 95 waiting times is picture = 5.38 and assume that σ, the standard deviation of the population of all customer waiting times, is known to be 2.25.

(a) consider the population of all possible sample means obtained from random samples of 95 waiting times. what is the shape of this population of sample means? that is, what is the shape of the sampling distribution of picture ?

normal because the sample is (click to select)smalllarge.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

it’s supposed to be -4+45=41

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
