Answer:
The P-value that will support this conclusion is 0.03.
Step-by-step explanation:
We are given the following hypothesis below;
Null Hypothesis,
: p = 50% {means that 50% of U.S. adults oppose the death penalty}
Alternate Hypothesis,
: p > 50% {means that majority (more than 50% of adults) oppose the death penalty}
Now, a survey was conducted in which a random sample of 1,100 U.S. adults are asked about their opinions on the death penalty, and based on the data, the researchers state, "at the 5% significance level, this survey provides strong evidence that the majority of U.S. adults oppose the death penalty.
The above information concluded that the null hypothesis has been rejected due to which we moves towards the conclusion that majority of U.S. adults oppose the death penalty.
<u>Now, the decision rule based on P-value criterion is given by;</u>
- If the P-value of test statistics is less than the level of significance, then we will reject our null hypothesis.
- If the P-value of test statistics is more than the level of significance, then we will not reject our null hypothesis.
Here, the P-value which will support our conclusion is 0.03 as at only this value our P-value is less than the level of significance of 0.05 and null hypothesis is rejected.
Answer:
$110
Step-by-step explanation:
If you invested $10,000 in a mutual fund and the fund earned a 7% return for the year, you’d gain about $700, and your investment would be worth $10,700. If you got an average 7% return the following year, your investment would then be worth about $11,500.
Over the years, your investment can really grow: If you kept that money in a retirement account over 30 years and earned that average 7% return, for example, your $10,000 would grow to more than $76,000.
In reality, investment returns will vary year to year and even day to day. In the short term, riskier investments such as stocks or stock mutual funds may actually lose value. But over a long time horizon, history shows that a diversified growth portfolio can return an average of 6% to 7% annually. Investment returns are typically shown at an annual rate of return.
