Answer: 95% confidence interval would be (0.013,0.167).
Step-by-step explanation:
Since we have given that
survey of teachers found that 224 of 395 elementary school teachers,
So, n₁ = 395
x₁ = 224
So,
n₂ = 266
x₂ = 126
So,
At 95% confidence level, z = 1.96
So, interval would be
Hence, 95% confidence interval would be (0.013,0.167).
Answer:
The length of side A in the enlarged trapezoid is 12 cm.
Answer: If Gregg colored none of the numbers blue, then obviously the chance the of his coloring being factorific would be zero.
If Gregg colored all of his cards blue, then again the chance would be 100%. This is because at least one of the cards is blue and all the divisors are blue.
On the other hand if only some of the cards are blue, then are numerous possibilities for the probability. You would have to create a chart and analyze each option to make sure the divisors were also blue.
