Answer:
Between 15.95 ounces and 16.15 ounces.
Step-by-step explanation:
We have the following value m, being the mean, sd, being the standard deviation and n, the sample size:
m = 16.05
sd = 0.1005
n = 4
We apply the formula of this case, which would be:
m + - 2 * sd / (n ^ 1/2)
In this way we create a range, replacing we have:
16.05 + 2 * 0.1005 / (4 ^ 1/2) = 16.1505
16.05 - 2 * 0.1005 / (4 ^ 1/2) = 15.9495
Which means that 95% of all samples are between 15.95 ounces and 16.15 ounces.

Answer:
B. Subtract 7
Step-by-step explanation:
You always want to isolate the <em>x</em> term to solve for <em>x</em> in any equation. Therefore, we need to move the 7 to the other side. Only way to do that is to subtract 7 on both sides.
Answer:
336 total slices
Step-by-step explanation:
60% of 30 = 18
18 * 12 = 216
40% of 30 = 12
12 * 10 = 120
216 + 120 = 336
Answer:
Negatively skewed
Step-by-step explanation:
Arrange this data in ascending order:
46, 50, 57, 58, 59, 59, 65, 66, 77, 80
and draw the bar chart as shown in attached diagram.
The data distribution appears to be negatively skewed (or left skewed), because the scores fall toward the higher side of the scale and there are very few low scores. The mean is also to the left of the peak.
