Answer:
Total no. of buttons = 300 + 700 + 1000
+ 500 = 2500
Possibility for a person to pick a pink button = 300/2500 = (3/25)%
Amount of pink buttons she can expect her friends to pick = 50(3/25) = 6
She can expect to make 6 pink barrettes

1)360 (400*.9)
2)342 (380*.9)
3)119 (140*.85)

Answer: (3.3, 3.5)
Step-by-step explanation:
The formula to calculate the confidence interval is given by :-
, where 
= sample mean.
z* = critical value.
= Population standard deviation.
n= Sample size.
As per given , we have
n= 217
By using z-table , the critical value for 95% confidence level : z* = 1.96
Now, the 95% confidence interval for the mean consumption of meat among males over age 50 will be :
Hence, the 95% confidence interval for the mean consumption of meat among males over age 50 =(3.3, 3.5)
Answer: 8
<u>Step-by-step explanation:</u>
60 dowels - each 6 inches (1/2 foot) in length = 30 feet of wood
