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)
Answer:
The answer is "32 and 48"

The perimeter is= sum of sides
Calculating the Area of base
1 in 12 because there’s a 1 in 2 you’ll get head or tails and a 1 in 6 to get any of the numbers
Answer:
Step-by-step explanation:
Add or subtract like terms.
Answer:
Solution given:
we have
y=5x-1
equating equation with y=mx+c
we get
slope [m]=5
we have
for parallel
slope are equal
So
<u>the</u><u> </u><u>required</u><u> </u><u>slope</u><u> </u><u>is</u><u> </u><u>5</u><u>.</u>
