BaLLatris [955]

Answer:

10,600

Step-by-step explanation:

The bacteria grew in 2 hours by 800. Divide that and that it by 400 per hour.

Since it is a proportional rate, we can assume that the rate continue through till midnight.

Since midnight is 12 hours after noon then the bacteria grow 400 (12)=4800.

We add this to the population at noon 5800+4800=10,600.

When you calculate the sample size for a proportion, you use an estimate for the population proportion; namely . A conservative

LuckyWell [14K]

Answer: A. 0.50

Step-by-step explanation:

The formula to find the sample size : $n=p(1-p)(\dfrac{ z^*}{E})$

, where p= Prior estimate of population proportion.

E= Margin of error

z* =Critical z-value.

When , we do not have prior estimate of population proportion , we use p= 0.5 because at p=0.5 it gives the maximum same sample size for the corresponding confidence interval and margin of error.

Therefore , the conservative value for n can be obtained by using p=0.50.

Therefore , the correct answer is A.0.50 .
