The correct answer is CI = (71.415%, 78.915%)
The correct option is (A)
<h3 /><h3>What is Confidence level?</h3>
A confidence interval is the mean of your estimate plus and minus the variation in that estimate.
Given:
x = 376
Sample = 500 students
CI= [(376/500-1.96 √((376/500)*(124/500)/500) , (376/500-1.96
√((376/500)*(124/500)/500)]
CI = (71.415%, 78.915%)
Hence, CI = (71.415%, 78.915%)

Inverse Functions. An inverse function goes the other way! Let us start with an example: Here we have the function f(x) = 2x+3, written as a flow diagram: The Inverse Function goes the other way: So the inverse of: 2x+3 is: (y-3)/2 .
Answer:
Step-by-step explanation:
1: theoretical probability for flipping a coin is thats because there are only 2 options and only one will happen theoretically you should get 50 out of 100 should be heads. but getting 41 out of 100 is a bit low
theoretically 50/100
in actuality 41/100
2. Part A: I believe the chance of hitting the black dot is closer to zero due to the amount of white background there is. There is a lot more white then black.
Part B: The probability of hitting the white is closer to 1 due to the greater amount of white on the target than the amount of black. There is a lot more white than black.
Answer:
Terms are 2 , 3 , 7 , 31
Step-by-step explanation:
1) given a1 = 2
an+2 = 2(an) -1
put n = 1
a1 + 2 = 2a1 -1
put value of a1 in above
you'll get a3 = 2² -1
a3 = 4-1
a3 = 3
put n = 3
a3 + 2 = 2a3 -1
a5 = 2³-1
a5 = 8-1
a5 = 7
put n = 5
a5 + 2 = 2a5 -1
a7 = 2⁵ -1
a7 = 32 -1
a7 = 31
Hope you got it.
Similarly you can find 2nd one's term t23
tn = 5*n -4
here n = 23
t23 = 5 * 23 - 4
t23 = 115 -4
t23 = 111
Hope this helps you.
