1 answer:
Empirical probability is computed by running an experiment multiple times (in this case, asking the same question to many people), and then computing the ratio
In this case, 236 people over 991 said that they checked the portfolio daily, so the empirical probability is
Which you can round as 0.238, i.e. 23.8%.

Answer:
s = 19.7
Step-by-step explanation:
First we need to calculate the mean x' of the sample as:
We sum all the scores and divide them by the number of scores.
Then, the standard deviation s is calculated as:
We square every score less the mean, sum every value, then divide that by the number of scores less 1 and finally, we calculate the square root.
So, the standard deviation of the sample is 19.7
Answer:
x = 1 ⇔ y = -2.4
x = 2 ⇔ y = -1.8
x = 3 ⇔ y = -1.2
x = 4 ⇔ y = -0.6
Step-by-step explanation:
→ Rearrange to make y the subject
→ Multiply everything by -1
→ Divide everything by 5
⇒ Substitute x = 1, 2, 3 and 4
