Answer:
31.25 miles
Step-by-step explanation:
5 miles is 8 kilometers. 5/8= 0.625. This means that 1 kilometer is 0.625 miles. To find how many miles are equal to 50 kilometers, simply multiply 50 and 0.625 to get 31.25 miles.
The mean (average) of a data set is found by adding all numbers together and then dividing by the number of values in the set.
Median is the middle value when the numbers are ordered from least to greatest.
We want to find the value of t such that the area to the left of −|t| plus the area to the right of |t| equals 0.1.
That is level of significance (α) = two-tail area = 0.1
<u>what is a level of significance in research?</u>
The significance stage (also called kind I mistakes rate or the extent of statistical importance) refers back to the chance of rejecting a null hypothesis that is in truth true. This amount stages from 0 (0.0) to at least one (1.zero) and is generally denoted through the Greek letter alpha (a).
<u>What are the three </u><u>levels of significance</u><u>?</u>
commonplace importance stages are 0.10 (1 risk in 10), 0.05 (1 risk in 20), and zero.01 (1 hazard in one hundred). The result of a speculation check, as has been seen, is that the null hypothesis is both rejected or now not.
