Answer:
So the answer for this case would be n=67 rounded up
Step-by-step explanation:
Information given
represent the sample mean for the sample
population mean
represent the sample standard deviation
n represent the sample size
Solution to the problem
The margin of error is given by this formula:
(a)
And on this case we have that ME =400 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The critical value for 98% of confidence interval now can be founded using the normal distribution. And the critical value would be
, replacing into formula (b) we got:
So the answer for this case would be n=67 rounded up
The answer is A because The Commutative Property of Addition states that no matter how the problem is structured you would still get the same answer and answer A expresses that
The graph that can represent the data most accurately is (a) The y-axis of a bar graph starts at zero fish. One bar is 24 units, another bar is 51 units, and the third bar is 36 units
The given parameters are:
- Aquarium A: 24 fishes
- Aquarium B: 51 fishes
- Aquarium C: 36 fishes
The above dataset can be represented on a bar graph, where the lengths of the bars represent the number of fishes in each aquarium
Hence, the graph that can represent the data most accurately is (a)
