Answer:
Sample size minimum is 60
Step-by-step explanation:
given that you want to create a 99% confidence interval with a margin of error of .5.
The population standard deviation is equal to 1.5
i.e.
Confidence level = 99%
Since population std deviation is known, we can use Z critical value for finding margin of error
Z critical value for 99% = 2.58
Margin of error =
Equate this to 0.5 and solve for n
Answer:
Air pressure =
Step-by-step explanation:
Relationship between air pressure and altitude can be modeled by,
P = 14.7e
Where P = Air pressure
and h = altitude above the sea level
Air pressure on Mount Everest having altitude = 29028 feet abve the sea level will be,
P =
=
= 4.603
≈ 4.6
Therefore, air pressure on Mount Everest = 4.6
<em><u>Solution:</u></em>
Given that,
<em><u>The label on a 1-kilogram can of mixed nuts states that a serving size is 40 grams</u></em>
From given,
Total = 1 kg
We know that,
1 kg = 1000 grams
Serving size = 40 grams
<em><u>How many servings are there in the can?</u></em>
Thus there are 25 servings
