Answer:
Step-by-step explanation:
its D
<span>21.72%
The 68-95-99 rule states that 1 standard deviation from the mean will contain 68% (68.27 more specifically) of all data points. For each sample, we multiply the success rate for </span>.6827*.6827*.6827*.6827 =.2172 or 21.72%
Trial and error specifies that you should guess the value of m and see if you aimed too low too high then adjust your next guess based on that.
Suppose we don't already know what m is (even though it is completely obvious), let's pick m to be 6,
So we check,
but
which means m must be bigger.
So we pick m to be 8 and check,
but
which means m must be smaller.
Since only natural number between 6 and 8 is 7 we pick m to be 7 and check,
and
.
The answer is therefore 7.
Hope this helps :)
Answer:
10.5
Step-by-step explanation:
4.50 ÷ 3 = 1.5
1.5 × 7 = 10.5
Arranging in ascending order we have
52 55 59 60 62 65 65 66
The median = (60+62)/2 = 61
The mean = 484 / 8 = 60.5
range = 66-52 = 14
interquartile range = 65 - 57 = 8
pairs = 65
