Question

A united nations report shows the mean family income for mexican migrants to the united states is $28,540 per year. a floc (farm labor organizing committee) evaluation of 26 mexican family units reveals a mean to be $30,500 with a sample standard deviation of $10,500. does this information disagree with the united nations report? apply the 0.01 significance level. a. state the null hypothesis and the alternate hypothesis.

Answer 1

The null hypothesis (H0) would be that the mean family income for Mexican migrants to the United States is $28,540 per year, as stated in the United Nations report. The alternate hypothesis (Ha) would be that the mean family income for Mexican migrants differs from $28,540 per year.

Step-by-step explanation:

The null hypothesis (H0) in this case would be that the mean family income for Mexican migrants to the United States is $28,540 per year, as stated in the United Nations report. The alternate hypothesis (Ha) would be that the mean family income for Mexican migrants to the United States differs from $28,540 per year.

To determine whether the FLOC evaluation disagrees with the United Nations report, we can conduct a hypothesis test. We'll use a significance level of 0.01. Here are the steps:

1. Null hypothesis (H0): The mean family income for Mexican migrants to the United States is $28,540 per year.
2. Alternate hypothesis (Ha): The mean family income for Mexican migrants to the United States differs from $28,540 per year.
3. Calculate the test statistic using the formula: t = (sample mean - population mean) / (sample standard deviation / sqrt(sample size)).
4. Find the critical value(s) for a two-tailed test with a significance level of 0.01 using a t-table or a t-distribution calculator.
5. Compare the test statistic to the critical value(s).
6. If the test statistic falls outside the critical value(s) region, reject the null hypothesis. If the test statistic falls inside the critical value(s) region, fail to reject the null hypothesis.

Based on the given information, you can now perform the hypothesis test to determine whether the FLOC evaluation disagrees with the United Nations report.
