What is approximate estimation?
If an estimation, or estimate, is a guess, an approximate estimation is a rougher guess.
What 6 numbers has a median of 18?
There are infinitely many sets. One possibility is {18, 18, 18, 18, 18, 18}.
Another is {15, 16, 17, 19, 20, 21} or {-5000, -4999, -4998, 5034, 5036, 1,000,000,000,000,000}
What is probability of at least 2 heads on tossing 3 coins?
There are 8 permutations of three coins. Of these, 3 of them have two heads, so the probability of tossing two heads on three coins is 3 in 8, or 0.375.
However, you said, "at least", so that includes the case of three heads, so the probability of throwing at least two heads is 4 in 8, or 0.5.

Small samples and large population variances imply that the estimate for the mean will be relatively poor. Whether or not it will result in an underestimate or overestimate depends on the distribution: with a symmetric distribution the two outcomes are equally likely.
How do you figure the percentage in a frequency table?
You find the total of all the frequencies, N.
Then the percentage for any frequency is 100*frequency/N.
How do you describe distribution?
Distribution refers to the way in which values or data points are spread or arranged across a range. It can be characterized by its shape (e.g., normal, skewed), central tendency (mean, median, mode), and variability (range, variance, standard deviation). Understanding distribution is crucial in statistics as it helps to interpret data, identify patterns, and make predictions. Visualization tools like histograms or box plots are often used to illustrate the distribution of data.
How do you calculate the accident frequency rate?
No. of Accident*(Ref.Value)/(total working man-hours)
Ref. Value=100 (Number of worker) * 45 (number of working hours per week) * 50 (number of working weeks a year)
Result = 225 000
if you accept number of working hours per week=40
result will be = 200 000

only 1 because the wqhen you rollthe 2nd 6 you have to move the pawn u took out
You have a 3.125% chance of not rolling an even number, because each time you roll a die you have a 50% chance of not rolling an even number, but each additional time you roll a die your chances of not rolling an even number the formula changes from 3/6 to 3/12 because the possibilities double but your chances of not rolling an even remain the same so eventually we end up with 3/96 because of rolling the die 6 times.
