Step-by-step explanation:
Confidence interval:
x% confidence
Of a sample
Between a and b.
Interpretation: We are x% sure(or there is a x% probability/chance) that the population mean is between a and b.
In this question:
I suppose(due to the options) there was a small typing mistake, and we have a 98% confidence interval between 0.56 and 0.62.
Interpreation: We are 98% sure, or there is a 98% chance, that the true population proportion of customers who click on ads on their smartphones is between 0.56 and 0.62. Option d.
Answer: a
Step-by-step explanation:
did the test
Then the approximate distance between the points is 4.47 units.
<h3>What is the approximate distance between points G and H?</h3>
We have the points G(1, 4) and H(3, 0), to get the distance between them we use the distance formula, we will get:

And we know that √20 ≈ 4.47
Then the approximate distance is 4.47 units.
