Answer:
The interval will be narrower if the researchers increase the sample size of droplets.
Step-by-step explanation:
The confidence interval can be obtained using the relation :
Xbar ± Margin of error
Margin of Error = Zcrit * s/sqrt(n)
Zcritical = critical vlaue at the specified α - level
n = sample size ; s = standard deviation
Sample size being the denominator, will reduce the overall value of the error margin as we utilize a larger sample.
Hence, the interval becomes narrower as the error margin is reduced which is achieved by employing an increased sample size.
