A study of womenâ€™s weights found that a randomly selected sample of 234 women had a mean weight of 157.3 lb. Assuming that the

Answer:

(155.301 ; 159.299)

Step-by-step explanation:

Xbar = 157.3

Sample size, n = 234

Population standard deviation, σ = 15.6

The confidence interval :

Xbar ± standard Error

Standard Error = Zcritical * σ/√n

Zcritical at 95% = 1.96

Standard Error = 1.96 * (15.6/√234) = 1.999

Lower boundary : 157.3 - 1.999 = 155.301

Upper boundary : 157.3 + 1.999 = 159.299

(155.301 ; 159.299)

I NEED HELP WITH THIS PLEASE HELP ME

Answer:

156 minutes

Step-by-step explanation:

So we need to create an equation to represent how Frank's phone company bills him

I will denote "y" as the total for his bill
I will denote "x" as the number of minutes Frank uses

So the phone company charges an $8 monthly fee, so this value remains constant and will be our "y-intercept"

They then charge $0.06 for every minute he talks, this will be our "slope"

Combining everything into an equation, we have: y = 0.06x + 8

Now since we were given Franks phone bill total and want to figure out how many minutes he used, we just need to solve the equation for x and plug in our known y value

y = 0.06x + 8 → y - 8 = 0.06x → $x=\frac{y-8}{0.06}$
Then plugging in our y value we get $x=\frac{17.36-8}{0.06}=\frac{9.36}{0.06}= 156$

Frank used up a total of 156 minutes
