Answer:
The value of the test statistic is 
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the sample mean, 
is the value tested at the null hypothesis, 
is the standard deviation and n is the size of the sample.
In this problem, we have that:
Then
The value of the test statistic is
Answer:
4 will replace?
Step-by-step explanation:
as 3-2=1
6-4=2
4-1=3
8-2=6
again
3-2=1
so
6-x=2
6-2=x
4

Use PEMDAS
Answer:the price for one shirt is $20
the price for one pair of pants is $12
Step-by-step explanation:
The question is incomplete. The complete question is
A shopper purchased 8 t shirts and 5 pairs of pants for $220. The next day he purchased 5 t shirts and 1 pair of pants for $112. How much does a t shirt and each pair of pants cost.
The solution is
Let x represent the price for one t shirt.
Let y represent the price for one pair of pants.
A shopper purchased 8 t shirts and 5 pairs of pants for $220. This means that
8x + 5y = 220 - - - - - - - - - -1
The next day he purchased 5 t shirts and 1 pair of pants for $112. This means that
5x + y = 112 - - - - - - - - - - - 2
Multiplying equation 1 by 5 and equation 2 by 8, it becomes
40x + 25y = 1100
40x + 8y = 896
Subtracting, it becomes
17y = 204
y = 204/ 17 = 12
Substituting y = 12 into equation 2, it becomes
5x + 12 = 112
5x = 112 - 12 = 100
x = 100/5 = 20
Answer:
Can not be determined.
Step-by-step explanation:
We can easily notice that the limit is x tends to infinity, whereas x is not present in the given function, we are given (1 + 1/n). So we can not evaluate the given limit for x as parameter, we must have some function of x to solve this problem.
Hence, option C is correct i.e. the limit can not be determined.
