Answer:
D
Step-by-step explanation:
p +/- [z + sqrt(pq/n)]
0.65 + [1.645 × sqrt[0.65 × (1-0.65) ÷ 50]
0.65 +/- 0 1109613165
[0.5390386835 , 0.7609613165]

Answer: There are 249 times Jamie takes a counter from the bag.
Explanation:
Since we have given that
Ratio of colour of red to blue to green is 1:3:7.
Number of blue counters = 68
Let the total number of times Jamie does from the bag be x.
So, According to question,
![\frac{3}{11}\times x=68\\\\x=\frac{11}{3}\times 68\\\\x=249.33\\\\=249\ approx.](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B11%7D%5Ctimes%20x%3D68%5C%5C%5C%5Cx%3D%5Cfrac%7B11%7D%7B3%7D%5Ctimes%2068%5C%5C%5C%5Cx%3D249.33%5C%5C%5C%5C%3D249%5C%20approx.)
Hence, there are 249 times Jamie takes a counter from the bag.
