The elevation E, in meters, above sea level at which the boiling point of a certain liquid is t degrees Celsius is given by the

otez555 [7]

Given function is

$E(t) = 1100(80 - t) + 500(80 - t)^2$

At t= 79.5 degree.

So we can place t= 79.5 in given equation

$E(79.5) = 1100 (80 - 79.5) + 500* (80 - 79.5)^2
$
= $1100 * 0.5 + 500 * (0.5)^2$
= $550 + 500 * 0.25$
= $550 + 125 = 625$

So elevation equal to 625 meter at t = 79.5 degree.

An agency is studying the income of store managers in the retail industry. A random sample of 25 managers reveals a sample mean

aalyn [17]

Answer:

The Confidence Interval = ($44,745.55 , $46,094.45)

Step-by-step explanation:

The formula for Confidence Interval =

Confidence Interval = Mean ± z × Standard deviation/√n

Where n = number of samples = 25 managers

Standard deviation = $2,050

Mean = $45,420

z = z score of the given confidence interval

= z score of 90% confidence interval

= 1.645

Confidence Interval = $45,420 ± 1.645 × $2,050/√25

= $45,420 ± 1.645 × $2,050/5

= $45,420 ± 674.45

Confidence Interval =

$45,420 - 674.45 = $44,745.55

$45,420 + 674.45 = $46,094.45

Therefore, the Confidence Interval = ($44,745.55 , $46,094.45)
