Cranberry Juice is a homogenous solution.
<h3>
What is a Homogeneous Solution?</h3>
A solution is defined as mixture in which the solute is uniformly dissolved in a solvent.
A Homogeneous mixture is a solution in which all components are uniformly distributed and its components cannot be separated by chemical means and one cannot physically see one or more components.
Here,Cranberry juice is a solution because it contains many constituents like
- cranberry fruit
- sugars
- natural chemical
- additives all dissolved in a solution.
it is also a Homogeneous as one cannot see all its constituents, neither can its components be separated by chemical means .

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
