Jessica's school bus stop is 60 yards from her house. For a normal school week, how many feet will Jessica walk to and from the bus stop.

Answers

Answer:

1,800 feet

Step-by-step explanation:

Assuming that the normal school week is 5 days, she will walk for 5 days to and from. Each day she will walk 120 yards to and from the stop. Multiply that number by 5 and you get your answer of 600 yards. The answer is wanted in feet, so you have to consider yards to feet conversions. 1 yard is three feet. Therefore, you multiply 600 by 3 and you get your answer in feet.

choose yes or no to tell whether each of the following describes a convenience sampling method​

Answers

No, this is systematic sampling. Systematic sampling is where you use a specifically well defined rule to generate your sample. In this case, that rule is "pick every 4th customer". In other words, if the customer number is a multiple of 4, then they are selected.No, this is simple random sampling (SRS). Each school is assigned a number, and those numbers are fed into a computer to generate a list of schools to form the sample. A random number table can also be used. When comparing to systematic sampling, SRS in my opinion is the stronger sampling method in that we get a better representative sample. Consider a case where on some unlucky circumstance that every 4th customer happens to be male (refer to problem 1). That would mean males are over-represented while females are completely under-represented. This example, while a bit extreme, shows a flaw in systematic sampling. So in short, it's best to use SRS if you could only pick one.  Yes, this is convenience sampling. As the name strongly implies, convenience sampling is the easiest or most convenient way to select a sample. Sheila simply looked to her left and right to get the sample points she needed. While it's tempting to use this method due to its ease, it's probably very clear that this method can be heavily biased. She should employ SRS to get a better representative sample.Yes, this is convenience sampling. For the quality control manager, the easiest most convenient ladders he found were the first five closest to him. Those five ladders may or may not be representative of the population. The population being the set of all ladders in the shop. If those ladders don't break, then the manager may get the wrong conclusion that all if not most of the ladders won't break. However, his sample is not representative and there may be bad faulty ladders in the shop somewhere. He should do a SRS to address this problem. Perhaps even a cluster sample where he breaks the shop's floor area into various chunks and does random sampling based on that. A cluster sample is useful because some areas of the shop may be better or worse off compared to others. Eg: if there's a leak in the roof in one spot, or if there's more moisture, then that cluster is different from the rest that don't have such issues.

In short, we have these answers in this exact order: No, No, Yes, Yes.

To determine whether the pipe welds in a nuclear power plant meet specifications, a random sample of welds is selected, and tests are conducted on each weld in the sample. Weld strength is measured as the force required to break the weld. Suppose the specifications state that mean strength of welds should exceed 100 lb/in2; the inspection team decides to test
H0:μ=100 versus Ha:μ>100.
Explain why it might be preferable to use this Ha rather than μ<100.
A. We want to determine if there is significant evidence that the mean strength of welds differs from 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is not satisfied.
B. We want to determine if there is significant evidence that the mean strength of welds is less than 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is not satisfied.
C. We want to determine if there is significant evidence that the mean strength of welds exceeds 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is satisfied.
D. We want to determine if there is significant evidence that the mean strength of welds equals 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is satisfied.

Answers

Answer:

C. We want to determine if there is significant evidence that the mean strength of welds exceeds 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is satisfied.

Step-by-step explanation:

Given

[tex]\mu = 100[/tex]

[tex]H_0:\mu = 100\\\\H_a:\mu > 100[/tex]

Required

State why it is preferred to [tex]Ha: \mu < 100[/tex]

From the question, we understand that the initial test is the force required to break the weld.

This represents the null hypothesis

Because the required force can not be less than the strength of the weld (it must match the force keeping the weld), the null hypothesis is represented as:

[tex]H_0:\mu = 100[/tex]

Reading the question further;

The specification requires that the mean strength should exceed 100

In inequalities, exceeds means greater than, and it is represented with >

So, the null hypothesis is rightly represented as:

[tex]H_a:\mu > 100[/tex]

Hence: (c) is true

You are given data on number of radio ads and sales for a local department store. You had observations for 20 months. The correlation between ads and sales is 0.40. Does this indicate a positive and significant relationship between ads and sales at the 5% level of significance

Answers

Answer:

"No" would be the appropriate response. A further explanation is provided below.

Step-by-step explanation:

According to the question,

Number of observations,

n = 20

Significance level,

d = 5%

i.e.,

= 0.05

Calculated correlation,

= 0.40

Critical correlation value will be:

=  0.444

According to the question, we can see that the calculated correlation i.e., "0.40" is far less than the critical correlation value i.e., "0.444". The null hypothesis has always been not rejected. Thus it doesn't indicate the significant relationship.

So the above it the right response.

"0.7769" is the right approach. A further explanation is given below.

Step-by-step explanation:

According to the question,

The parameter for the exponential distribution,

μ = 6

x = 9

Now,

⇒  [tex]P(X < 9) = 1 - exp ( \frac{-x}{\mu} )[/tex]

On substituting the given values in the above equation, we get

⇒                  [tex]= 1 - exp (\frac{-9}{6} )[/tex]

⇒                  [tex]=1-exp(-1.5)[/tex]

⇒                  [tex]=1-0.2231[/tex]
