-interval for a difference between means (cotton candy minus mango) was constructed. Based on the interval, there was convincing statistical evidence of a difference in population mean flavor ratings, with mango having the greater sample mean rating. Which of the following could be the constructed interval?
The constructed interval for the rating of the ice cream mango and cotton candy is (-1.4-2.6). The correct option is C.
What is t-interval?When the sample size is small and the population standard deviation is unknown, the T interval is useful.
The Z-interval for calculating confidence intervals becomes less reliable when the sample size is very small (n=30).
And this is where the T-interval comes in.
Thus, the correct option is C, (-1.4-2.6).

The t-test tests for:
The t-test is a statistical test used to determine if there is significant statistical evidence for a difference in means between two groups.
Essentially, what this means is that it's used to figure out whether or not two groups have different means. When we run a t-test, it returns to us a t-score and a P-value. P-value is derived from the t-score, and this P-value is essentially the probability that the null hypothesis would produce the observed results displayed in the question. In order to determine if we should reject or fail to reject our null hypothesis, the P-value determined by the t-test should be lower than the significance level. If the question doesn't prompt for a specific significance level (which is usually displayed symbolically as α), then we can generally use 0.05 as the significance level.
I'll admit, this whole concept is pretty confusing. Statistics is a surprisingly hard class. If you have any questions about anything I wrote here or would like me to explain any concept I mentioned further, don't be afraid to ask me!

Assume the economy is currently in long-run equilibrium. An increase in the money supply will affect unemployment in the short run and in the long run in which of the following ways?
A money supply go up and be inflationary in nature if the unemployment rate is below the natural rate and thus there will be high rate of unemployment.
What does it implies when the economy is in long run equilibrium?An economy that is to be in long-run equilibrium will have the real unemployment rate to be equal to that of natural rate of unemployment.
Note that a boast in the money supply will influence unemployment based on the fact that unemployment rate is bigger than the natural rate of unemployment, and thus the rate of inflation is said to be going done.
When the level of output is higher than employment output, an unemployment rate tends to increase and thus pressure is placed on increased wages and prices.
Conclusively, Note that Lower unemployment rate will lead to lower presence of workers in the companies .

2. Which statement is a complex sentence?
After the storm subsided, I surveyed the house for damage. O
I really wanted to go to my friend's house, but I stayed home.
The house sustained some damage as a result of the storm. O
I brought lumber to fix the damage; my father brought tools.
Answer:
A.
Explanation:
1. Complex sentence: Has one independent clause and 1 (or more) dependent clauses
2. Clause: Contains a subject and verb
3. Independent Clause: Taking the clause out of the sentence would make sense as a sentence on its own.
4. Dependent Clause: Even though it has a subject and verb, it doesn't make sense as a sentence.
Not B: This is a compound sentence. It has 2 independent clauses. I know this because If you take "I really wanted to go to my friend's house" and "I stayed at home," they can be their own sentence.
Not C: This is similar to a complex sentence, so it can be trickier. It's not because "as a result of the storm" doesn't have a subject or verb so it's nto a clause.
Not D: Before and after the semicolon can be their own sentence. Because they're both independent, it's compound and not complex.
It's A: "After the storm subsided" doesn't make sense by itself, but it has a subject (storm) and verb (subsided). That makes it dependent. The other is independent because it makes sense as a sentence. Independent clause+dependent clause= complex.

Eliza has only one investment $15,000 in stock shares of iFruit Computing. The stock's annual returns for the last 10 years have averaged around 89. Evaluate the risk level of Eliza's Investment. Is there anything she can do to make her investment less risky? Explain your answer.
The risk level of Eliza's Investment is that it has a low standard deviation. To make the investment less risky is to withdraw from it.
Evaluation of risk levels of an investmentThe evaluation of risk levels in an investment can be done to ascertain whether to continue in an investment or to withdraw.
The methods that can be used to evaluate risk levels in an investment include the following:
alpha, beta, R-squared, standard deviation, and Sharpe ratio.The risk level of Eliza's Investment can be evaluated using the standard deviation method.
The price invested = $15,000 (p)
Time = 10 years
Rate = 8%
Therefore, the interest generated= 15,000 × 10×8 /100
= 1200000/100
= $12,000
Therefore in every year the interest of the investment she made will yeild only 12,000/10 = $1,200
The standard deviation is low because the rate of returns is low.
To avoid further risks, Eliza should withdraw from the investment because the rate of returns from the investment is too low.
