Answer:
The sampling used is simple random sampling.
Step-by-step explanation:
Consider the provided information.
Types:
- Simple random sample is a subset of the population chosen from a larger set. Every person is selected by chance and randomly.
- Systematic sampling: list of elements is counted off.
- Convenience sampling: data which is readily available is used. That is, the first people are running into by the surveyor.
- Cluster sampling: divide the population into groups, usually geographically.
- Stratified sampling: divide population into groups called strata. but this time population might be separated into males and females.
Here, randomly selected 60 customers, Thus, the sampling used is simple random sampling.
The deliberate termination of a human pregnancy, most often performed during the first 28 weeks of pregnancy.
A:
Table 1:
f(x) = 8x
X= cups so
ounces =
8* # of cups
Table 2:
f(x) =16x
X= pints so
ounces =
16*# of pints
Table 3:
f(x)= 32x
X= quarts so
ounces=
32*# of quarts
Note: another way instead of f(x)=kx is y=kx
B:
Depending on the slope we can easily find which is the steepest slope by easily comparing the slopes and seeing which is greater.
T1: 8
T2: 16
T3: 32
So, looking at our slopes, table 3 has the greatest slope because it has the greater slope out of the other two.
C:
The phrase, "rate of change" is another way to say the slope. To list again,
T1: 8
T2: 16
T3: 32
The table with the smallest slope would be table 1 since it is less than the other two tables.

Answer:
The value of the test statistic is -3.14.
Step-by-step explanation:
Test statistic:
In which X is the sample mean, 
is the expected value, 
is the standard deviation and n is the size of the sample.
A company advertises that its cans of caviar each contain 100 g of their product.
This means that 
They calculate a sample mean weight of 99 g and a sample standard deviation of 0.9 g. Sample of 8 cans.
This means that 
So the test statistic will be given by:
The value of the test statistic is -3.14.
