Answer: n = 14
Step-by-step explanation: margin of error = critical value × σ/√n
Where σ = population standard deviation = 1
n = sample size = ?
We are to construct a 99% confidence interval, hence the level of significance is 1%.
The critical value for 2 tailed test at 1% level of significance is gotten from a standard normal distribution table which is 2.58
Margin of error = 0.7
0.7 = 2.58×1/√n
0.7 = 2.58/√n
By cross multipying
0.7×√n = 2.58
By squaring both sides
0.7^2 × n = 2.58^2
0.49 × n = 6.6564
n = 6.6564/0.49
n = 14
Answer111
Step-by-step explanation:i111
Both of these variables represent a common measure used in chemistry.
The amount of material/volume is the material’s concentration.
The rate is the reaction is increase by altering the concentration.
Answer:
Henry does not make money if he does not sell any apples.
Step-by-step explanation:
Henry sells apples. The graph of the relationship between the price of apples and their total weight passes through the point (0,0) or origin.
Now, we have to clarify the meaning of the point (0,0) on the graph.
We choose from the options that Henry does not make money if he does not sell any apples.
Therefore, option D will be the correct one. (Answer)
