The answer is A) 2
work:12/2=6 4(2+1)=12
Answer: Lower CI=21-t(0.025, 16)*7/sqrt(17)=21-2.12*7/sqrt(17)=17.4
upper CI=21+t(0.025, 16)*7/sqrt(17)=21+2.12*7/sqrt(17)=24.6
Explanation: Because there both close and equal
The Confidence Interval of the given random sample survey is gotten as; CI = 13.755 ± 1.456
<h3>What is the confidence Interval?</h3>
We are given the hypotheses as;
Null Hypothesis; H₀: μ = 15
Alternative Hypothesis; Hₐ: μ ≠ 15.
where μ is the mean number of hours worked per week for all students at the college with part-time jobs.
We are told that it has a 95% confidence interval and degree of freedom of df = 25
From the t-table, the t-score = 2.06
The table gives us the standard error as 0.707 and sample mean of 13.755. Thus, we can find the confidence interval as;
CI = 13.755 ± 2.06(0.707)
CI = 13.755 ± 1.456

The memorable and vital aspects are:
- Hardship observed on Mexico's farms.
- The Desperation of workers on a Mexican mega-farm
- The use of Children to harvest crops and sacrifice their dreams in Mexico's fields.
