Starting salaries of 90 college graduates who have taken a statistics course have a mean of $43,993 and a standard deviation of
inysia [295]

Answer:

a) E = 2482.90

b) 99% Confidence interval: (41510.1,46475.9)

Step-by-step explanation:

We are given the following in the question:

Sample mean, \bar{x} =$43,993

Sample size, n = 90

Alpha, α = 0.051

Sample standard deviation, s = $9,144

a) The margin of error

Formula:

z_{critical}\text{ at}~\alpha_{0.01} = 2.576

E =z_{critical}\times \displaystyle\frac{s}{\sqrt{n}}\\\\E = 2.576\times \frac{9144}{\sqrt{90}}\\\\E = 2482.90

b) 99% Confidence interval:  

\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

43993 \pm 2482.90 = (41510.1,46475.9)

Explanation:

The question is in French language. The translation to English is:

<em>1 rabbit saw 6 elephants while going to the river. Each elephant saw 2 monkeys go towards the river. Each monkey holds 1 parrot in its hands.</em>

<em>How many animals are going to the river?</em>

Animal       amount

Rabbit            1

Elephants      6 (the rabbit saw 6 elephants)

Monkeys:       6 × 2 = 12 (2 monkeys per elephant)

Parrots:          12 × 1 = 12 (1 parrot per monkey)

                     =============================

Total:             1 + 6 + 12 + 12 = 31 animals ← answer
