e-lub [12.9K]

Answer:

(53.3; 56.1)

Step-by-step explanation:

Given that:

Sample size, n = 41

Mean, xbar = 54.7

Standard deviation, s = 5.3

Confidence level, Zcritical at 90% = 1.645

Confidence interval :

Xbar ± Margin of error

Margin of Error = Zcritical * s/sqrt(n)

Margin of Error = 1.645 * 5.3/sqrt(41)

Margin of Error = 1.362

Lower boundary = 54.7 - 1.362 = 53.338

Upper boundary = 54.7 + 1.362 = 56.062

(53.3 ; 56.1)

Answer:

B

Step-by-step explanation:

since y and x vary directly the equation relating them is

y = kx ← k is the constant of variation

to find k use any ordered pair from the list given

using x = 4 when y = - 2, then

k = \frac{y}{x} = \frac{-2}{4} = - 0.5 → B
