From the question, we understand that:
This means that, the middle number is 3 (when sorted)
So, we can conclude that (b) and (c) cannot be true because their middle numbers are 6 and 5 respectively
Next, is to determine the mean of (a) and (d)
The mean of a data is calculated as:
So, we have:
(a)
(d)
Option (a) is true, because it has:
Answer:
0.8239 is the population proportion of participants that tried quitting smoking.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 142
Participants that tried quitting smoking = 117
Parameter:
- A parameter is a numerical value that describes a population.
Population proportion can be calculated as:
0.8239 is the population proportion of participants that tried quitting smoking.
Answer: A. Mean of sampling means
Standard deviation of sampling means =
B. The probability that your sample has mean less than 165 is 0.1492 .
Given : The distribution of blood cholesterol level in the
population of young men aged 20 to 34 years is close to normal with
mean Mg/dl and standard deviation
mg/dl.
Sample size : n= 150
Let sample mean values.
A. The mean and the standard deviation of the distribution of the sampling means would be :
Mean of sampling means =
Standard deviation of sampling means =
The probability that your sample has mean less than 165 would be
Hence , the probability that your sample has mean less than 165 is 0.1492 .
