Answer:

Yes, the sample data provides convincing evidence to support this claim.

Step-by-step explanation:

if 975 out of 2755 were sent home to change then you divide 975/2755 = .35, this means .35 out of all employees were sent to change, because 1/3 = .33 and .35 > .33 the claim is correct.

Assume that adults have IQ scores that are normally distributed with a mean of 96.296.2 and a standard deviation 20.520.5. Find
Sergeeva-Olga [200]

Answer:

The first quartile of the IQ scores of adults is 82.26.

Step-by-step explanation:

The first quartile is the value that is greater than 25% of the observations and less than 75% of the observation.

The formula to compute the first quartile (Q₁) of a Normal distribution is:

Q_{1}=\mu-0.68\sigma

The mean and standard deviation of the IQ scores of adults are:

\mu=96.2\\\sigma=20.5

Compute the first quartile value as follows:

Q_{1}=\mu-0.68\sigma=96.2-(0.68\times20.5)=82.26

Thus, the first quartile of the IQ scores of adults is 82.26.
