From a sample of 37 graduate​ students, the mean number of months of work experience prior to entering an MBA program was 35.15.
kiruha [24]

Answer: (29.35, 40.95)

Step-by-step explanation:

Formula to find the confidence interval for population mean :-

\overline{x}\pm z^*\dfrac{\sigma}{\sqrt{n}}

, where \overline{x} = sample mean.

z*= critical z-value

n= sample size.

\sigma = Population standard deviation.

As per given , we have

\overline{x}=35.15

\sigma=18

n= 37

Using z-table, the critical z-value for 95% confidence = z* = 1.96

Then, the confidence interval for the population mean will be :

35.15\pm (1.96)\dfrac{18}{\sqrt{37}}

=35.15\pm (1.96)\dfrac{1.7}{6.08276}

=35.15\pm (1.96)(2.95918)

\approx35.15\pm5.80

=(35.15-5.80,\ 35.15+5.80)=(29.35,\ 40.95)

Hence, a 95​% confidence interval for the population​ mean = (29.35, 40.95)

The tree diagram represents an
olga_2 [115]

Using it's concept, considering the tree diagram, the probability of event C is given as follows:

P(C) = 0.26.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

Each node at the tree is a multiplication, hence the probability of event C is given as follows:

P(C) = 0.6 x 0.3 + 0.4 x 0.2 = 0.18 + 0.08 = 0.26.
