72 represents 6 "units", so divide by 6 to get the number of people in one "unit":
72/6 = 12
Now multiply by 5 to get the number of boys:
12 * 5 = 60 boys
The negative 4 in the parenthesis caused the graph to move four units to the right.
Answer:
Levene confidence intervals ( b )
Step-by-step explanation:
T- test should include all of the following in the results section except the Levene confidence intervals.The confidence intervals may be constructed for various power values using the binomial distribution.
The dependent measure , the size and the Homogeneity of variance test are all included in the results section of a t-test
This is a problem in "binomial probability." Either the archer hits his target or he does not. This experiment is performed 5 times (so that n=5), and the probability that the archer will hit the target is 0.7 (so that p=0.7).
We need to find the binomial probability that x=3 when the possible outcomes are {0, 1, 2, 3, 4, 5}.
You could use a table of binomial probabilities to evaluate the following:
P(5, 0.7, 3).
Alternatively, you could use a TI-83 or TI-84 calculator and its built-in "binompdf( " function.
I evaluated binompdf(5,0.7,3) and obtained the result 0.309.
