Step-by-step explanation:
Start on the x-axis, the horizontal one Start at (0,0), where the two lines meet. Then go over to the right 2 tic marks. Then go up the y-axis, the vertical one, 5 tic marks.
Answer:
The correct answer is:
the amount of difference expected just by chance (b)
Step-by-step explanation:
Standard error in hypothesis testing is a measure of how accurately a sample distribution represents a distribution by using standard deviation. For example in a population, the sample mean deviates from the actual mean, the mean deviation is the standard error of the mean, showing the amount of difference between the sample mean and the actual mean, occurring just by chance. Mathematically standard error is represented as:
standard error = (mean deviation) ÷ √(sample size).
standard error is inversely proportional to sample size. The larger the sample size, the smaller the standard error, and vice versa.
Collection 1, no of marbles = 125
Collection 2, no of marbles =36 fewer = 125-36 =89
Collection 3, no of marbles = 53 more =125+53 =178
Hence total marbles = 125+89+178
= 392
Given that he uses 14 trays to hold all the marables
Let us assume that he distributes equally all 392 marbles in 14 trays
Then marbles in each tray = 392/14 = 27
Thus division is used for finding out the no of marbles in a tray.
For finding out no of marbles in 3 trays, we get = 3x27 = 81 marbles
(Here direct variation is used)
Answer is 81 marbles
