Answer:
Step-by-step explanation:
Since population std deviation is not known, we use t critical value for testing of hypothesis.
a) 90% conf level when n =28
df = 27, t critical = 1.706
b) 95% 28
df =27 and t critical = 2.052
c) 90% and 15
df =14 and t critical = 1.761
d) 95% and n =15
df =14: t critical = 2.145
Count the distance d, which gives you 7.
Use Pythogarean theorem to find c:

Plug in the numbers:

c is 5.
Same thing with g:

g equals 5.66.
Answer:
(a) 7 essays and 29 multiple questions
(b) Your friend is incorrect
Step-by-step explanation:
Represent multiple choice with M and essay with E.
So:
--- Number of questions
--- Points
Solving (a): Number of question of each type.
Make E the subject of formula in 

Substitute 36 - M for E in 


Collect Like Terms


Divide both sides by -4


Substitute 29 for M in 


Solving (b): Can the multiple questions worth 4 points each?
It is not possible.
See explanation.
If multiple question worth 4 points each, then
would be:

Where x represents the number of points for essay questions.
Substitute 7 for E and 29 for M.


Subtract 116 from both sides



Make x the subject

Since the essay question can not have worth negative points.
Then, it is impossible to have the multiple questions worth 4 points

Answer:
is the inequality that reflect the relationship.
Step-by-step explanation:
Given:
Charge for rental = $100
Additional charge = $ 35
Minimum amount that can be spent = $280
To Find:
equations or inequalities that reflect the relationship = ?
Solution:
Let x be the minimum number of hours
then the charge will be
100 + (number of hours)(additional cost per hour)
That is
100 + 35x
Now the minimum charge amount is $280 So, The charge can be 280 or more than 280
