Aresearch scientist wants to know how many times per hour a certain strand of bacteria reproduces. he wants to construct the 98% confidence interval with a maximum error of 0.15 reproductions per hour. assuming that the mean is 10.8 reproductions and the standard deviation is known to be 1.8, what is the minimum sample size required for the estimate? round your answer up to the next integer.

782

Step-by-step explanation:

Given : Mean :

Standard deviation :

Margin of error :

Significance level :

Critical value :

Formula for sample size  :-

Hence, the minimum required sample size = 782

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
