Answer:
8.66
Step-by-step explanation:
X. 1. 2. 3. 4. 5. 6 are all the possible events when rolling a die. If it is a fair die then the probability of rolling any number is 1/6. So the probability of rolling at most a two is p(1)+ p(2)= 2/6 or 1/3
Answer: The first blank would be 71 and the second blank would be 32 and the 3rd blank would be 8
Step-by-step explanation: because on the first on it added by 7 so you would have to do the same for all of them.
<span>The slope of a line is defined as the rate of change on the vertical axis, divided by the rate of change on the horizontal axis, Δy/Δx. So for a horizontal line, the rate of change on the y axis is zero, this means that it's slope will be 0/Δx and for vertical line, x-axis does not change, which make the denominator 0 Δy/0.</span>
Answer:
The standard error increases and the width of the interval increases
Step-by-step explanation:
The variance is equal to the square of the standard deviation. An increase in variance will increase the standard deviation.
The width of the confidence interval can be defined as:
The width is proportional to the standard deviation, so when the variance increases, the standard deviation and also the width of the interval increases.
