The typical average price of gasoline should be $2.81 and not $2.69 because $2.69 is not the average of the sampled prices.
<h3>What is the mean of the sample?</h3>
We are given the prices of a gallon of gasoline from 5 gas stations surveyed as; $2.79, $2.99, $2.69, $2.89, and $2.69.
Thus, to calculate the mean, we will use the formula;
Mean = ∑x/n
Mean = (2.79 + 2.99 + 2.69 + 2.89 + 2.69)/5
Mean = 14.05/5
Mean = $2.81
Thus, the typical average price of gasoline should be $2.81 and not $2.69

Answer:
We will apply the formula of d=y- x/n+1
Let y be 2.2 and x be 2.1 and n= 16
Then 2.2-2.1/ 16+1
0.1/17
x+d= 2.1 + 0.1 = 2.2
x+2d= 2.1+2×0.1=2.3
x+3d= 2.1+3×0.1=2.4
x+4d= 2.1+4×0.1=2.5
x+5d=2.1+5×0.1=2.6
x+6d=2.1+6×0.1=2.7
x+7d=2.1+7×0.1=2.8
x+8d=2.1+8×0.1=2.9
x+9d=2.1+9×0.1=3
x+10d=2.1+10×0.1=3.1
x+11d=2.1+11×0.1=3.2
x+12d=2.1+12×0.1=3.3
×+13d=2.1+13×0.1=3.4
x+14d=2.1+14×0.1=3.5
x+15d=2.1+15×0.1=3.6
x+16d=2.1+16×0.1=3.7

Answer:
The best estimate is 32 out of 32 times, she will be early to class
Step-by-step explanation:
The probability of being early is 99% = 99/100 = 0.99
So out of 32 classes, the best estimate for the number of times she will be early to class will be;
0.99 * 32 = 31.68
To the nearest integer = 32
