Answer:
If there are 5000 bacteria in a colony right now, there will be 5000x2, or 10000 bacteria in the colony in 37 minutes.
If there are 10000 bacteria in the colony in 37 minutes, there will be 20000 bacteria in the colony in 74 minutes, as the bacteria doubles every 34 minutes.

Answer: Point of estimation = 32.60
Margin of error = 1.175.
95% confidence interval would be (81.95,84.45).
Step-by-step explanation:
Since we have given that
n = 49
Average = $32.60
Standard deviation = $5
We need to find:
1) Point of estimation for the mean of the population:
2) At 90% level of confidence, z = 1.645
Margin of error would be
So, Margin of error = 1.175.
3) At 90% level of confidence, interval would be
Hence, 90% confidence interval would be (31.43,33.76).
