Step-by-step explanation:
Part a
represent the significance level
df =15
Since is a right tailed test the critical value is given by:
And we can use the following excel code to find it: "=T.INV(0.9,15)"
Part b
represent the significance level
n=20 represent the sample size
First we need to find the degrees of freedom given by:
Since is a left tailed test the critical value is given by:
And we can use the following excel code to find it: "=T.INV(0.1,19)"
Part c
represent the significance level
n=18 represent the sample size
First we need to find the degrees of freedom given by:
The value of and
Since is a two tailed tailed we have two critical values is given by:
And we can use the following excel code to find it: "=T.INV(0.025,17)"
Using proportions, it is found that the average daily requirement for these adults is of 2080 calories.
--------------------
- Percentage problems are solved by proportions, using a rule of three.
- 1560 calories is 75% = 0.75 of the calorie requirement for many adults.
- How much is 100% = 1?
The rule of three is:
1560 calories - 0.75
x calories - 1
Applying cross multiplication:
The average daily requirement for these adults is of 2080 calories.
