Given:
Sample size, n = 40
Sample mean, xb = $6.88
Population std. deviation, σ = $1.92 (known)
Confidence interval = 90%
Assume normal distribution for the population.
The confidence interval is
(xb + 1.645*(σ/√n), xb - 1.645*(σ/√n)
= (6.88 + (1.645*1.92)/√40, 6.88 - (1.645*1.92)/√40)
= (7.38, 6.38)
Answer: The 90% confidence interval is (7.38, 6.38)
Marlene owes a total of $20,710.75 in taxes.
If we are using the same tax schedule then $95,000 belongs to this bracket:
Over - But not over - of the excess over -
$77,100 but not over $160,850.. 15,698.75 plus 28% 77,100
Get the 28% of the difference between $95,000 and $77,100:
$95,000 - $77,100 = $17,900
$17,900 * .28 = $5,012
$15,698.75 + $5,012 = $20,710.75
Set up a proportion here as the height over the shadow of the adult = to the height over the shadow of the baby. so you have 12/4.8 = height/2. cross multiply to get 12*2=4.8 times height, which is 24 = 4.8*height. divide both sides by 4.8 to get height = 5 feet
