Subtract 6 from 50:
50-6 = 44
Divide 44 by 2:
44/2 = 22
add 6:
22+6 = 28
There is 22 in the smaller class and 28 in the larger class.
Answer:
(a) 81st
=NORM.INV(0.81;0;1)
(b) 19th
=NORM.INV(0.19;0;1)
(c) 76th
=NORM.INV(0.76;0;1)
(d) 24th
=NORM.INV(0.24;0;1)
(e) 11th
=NORM.INV(0.11;0;1)
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
For this case we can find the percentiles with the Norm.inv function in Excel and we got:
(a) 81st
=NORM.INV(0.81;0;1)
(b) 19th
=NORM.INV(0.19;0;1)
(c) 76th
=NORM.INV(0.76;0;1)
(d) 24th
=NORM.INV(0.24;0;1)
(e) 11th
=NORM.INV(0.11;0;1)
Answer:
Step-by-step explanation:
so by the power of a power rule we know that when you raise a power to another power you have to multiply the powers.
so i my oponion it would be 3 to the 10th* -2/15*-1= 10 times 2/15*-2
which in my oponion should be 3 to the negative 4/15
