Answer:
In April 153 millimeters of rain fell on the banana farm.
Step-by-step explanation:
Given:
Farm received rain in March and April = 271 millimeters
Farm received rain in March = 118 millimeters.
We need to find rain received by farm in April.
It can be calculated by Subtracting rain received by farm in march with total rain received by farm in March and April with
Rain fell in farm in April = Farm received rain in March and April - Farm received rain in March = 271 -118 = 153 millimeters.
Hence Banana Farm received rain of 153 millimeters in April.

Step-by-step explanation:
We want to determine a 90% confidence interval for the mean amount of time that teens spend online each week.
Number of sample, n = 41
Mean, u = 43.1 hours
Standard deviation, s = 5.91 hours
For a confidence level of 90%, the corresponding z value is 1.645. This is determined from the normal distribution table.
We will apply the formula
Confidence interval
= mean +/- z ×standard deviation/√n
It becomes
43.1 ± 1.645 × 5.91/√41
= 43.1 ± 1.645 × 0.923
= 43.1 ± 1.52
The lower end of the confidence interval is 43.1 - 1.52 =41.58
The upper end of the confidence interval is 43.1 + 1.52 =44.62
Therefore, with 90% confidence interval, the mean amount of time that teens spend online each week is between 41.58 and 44.62
