The z-score is given by:
z=(x-mean)/s.d
the z-score giving us P(0.95)=1.96 and -1.96
thus;
-1.96=(x-1500)/300
-588=x-1500
x=-588+1500
x=912
also:
1.96=(x-1500)/300
588=x-1500
x=588+1500
x=2,088
therefore the sample size of the student picked will be given by:
2,088-912
=1,176
Answer:
14
Step-by-step explanation:
As you are only pulling out one marble, the colors are irrelevant; each marble has exactly one 'chance' at getting pulled out. There are 14 marbles, so there are 14 possible outcomes. [Based on how basic the problem is, I tried to stick to basic mathematical terms].
Answer:
4 shirts will cost about 25.32
Step-by-step explanation:
First, You can divide 19/3 and this will give you 6.33 repeating.
Next, you will assume that one shirt would cost $6.33.
Finally, Multiply by 4 to get the amount of four shirts.
Nope .42 is greater, .4 is closer to 1 then .2 have a great day and hope this helps
