775 steps divided by 12.5. minutes is 62 so his average steps per minute is 62 steps per minute
Answer: Mean of the sample proportion = 74.4
Standard deviation of the samnple proportion is 5.32.
Step-by-step explanation:
Given : A random sample of 120 is taken from a population of 10000.
Let n = 120
Also, from previous survey, it is believed that 62% of the population has an Instagram account.
i.e, population proportion : p = 0.62
Now , the mean of the sample proportin would be :

i.e. Mean of the sample proportion = 74.4
The standard deviation of the samnple proportion would be :

Thus , the standard deviation of the samnple proportion is 5.32.
Answer:

Step-by-step explanation:
What is unit price?- unit price is the cost of one item(which in this case is an apple)
5 apples- $1.30

= $0.26
The value of z is zero
Step-by-step explanation:
The slope is the steepness of the line.
The formula for slope is given by:

Here
(x1,y1) = (1,z)
(x2,y2) = (2,8)
So,

The value of z is zero
