In the order of operation, multiplying or dividing don't take preference over the other. So with them, you work from left to right.

This means for this question, you first divide, then multiply.

Use the standard normal distribution or the t-distribution to construct a 99% confidence interval for the population mean. Jus

vichka [17]

Answer:

(25.732,30.868)

Step-by-step explanation:

Given that in a random sample of 42 people, the mean body mass index (BMI) was 28.3 and the standard deviation was 6.09.

Since only sample std deviation is known we can use only t distribution

Std error = $\frac{s}{\sqrt{n} } =\frac{6.09}{\sqrt{42} } \\=0.9397$

$df = 42-1 =41$

t critical for 99% two tailed $= 2.733$

Margin of error $= 2.733*0.9397=2.568$

Confidence interval lower bound = $28.3-2.568=25.732$

Upper bound = $28.3+2.568=30.868$
