Estimate the unit rate to the nearest hundredth. $1.19=GRAPE JUICE 12 fl oz. The unit rate is about$_ per fluid ounce.
2 answers:
Answer:
<h2>The unit rate is about 10 cents per fluid once of grape of juice.</h2>Step-by-step explanation:
By given, we know that 12 fl oz of grape juice costs $1.19. We can use the rule of three to find the unit rate.
If 12 fl oz of juice costs $1.19, how much would cost one fluid once of juice.
Therefore, the unit rate is about 10 cents per fluid once of grape of juice.

Using the z-distribution, it is found that:
- The 95% confidence interval is of -1.38 to 1.38.
- The value of the sample mean difference is of 1.74, which falls outside the 95% confidence interval.
The confidence interval is:
In which:
is the difference between the population means.
- s is the standard error.
In this problem, we have a 95% confidence level, hence, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
The estimate and the standard error are given by:
Hence the bounds of the interval are given by:
1.74 is outside the interval, hence:
- The 95% confidence interval is of -1.38 to 1.38.
- The value of the sample mean difference is of 1.74, which falls outside the 95% confidence interval.
