Answer:
When doing square roots the opposite is squaring so, to find one that is more than 12 and less that 13 would be finding one that is in between √144 and √169
That leaves your answer as √150, because it is more than √144 (which is 12) and less than √169 (which is 13)
B √150
Hope this helps ;)
Answer:
a. There's a 95% chance that the true proportion is in the confidence interval.
Step-by-step explanation:
When we want to estimate a property of a population (a population's parameter), without surveying the population, we use samples.
Then, with the information of the samples we can calculate the statistics and infere properties about a population. This inferences obviously came with some uncertainty, depending on the properties of the sample and specially the sample size.
When we talk about confidence intervals, we use the statistic of the sample (in this case, the mean) to estimate a range of values it is expected to find the true mean of the population. The width of this interval depends on the sample standard deviation and the sample size.
The value of the confidence interval (95%, 99%, etc) represent the probabilty that the true mean is within this interval.
19.8 I think and I'm pretty sure I have it right

Given the mass of each box, and the total number of boxes, multiply both quantities to obtain the total mass, as shown below
Therefore, the answer is 24kg.
