Answer:

\boxed {\boxed {\sf Ben \ \& \ Jerry's }}

Step-by-step explanation:

We are asked to find which ice cream is a better buy. We will compare the unit prices or price per ounce.

The unit price is found by dividing the price by the number of ounces.

1. Haagen - Dazs

unit \ price = \frac{price}{ounces}

This ice cream costs $5.04 for 14 ounces.

unit \ price = \frac{\$5.04}{14 \ oz}

unit \ price = \$ 0.36 /oz

2. Ben & Jerry's

unit \ price = \frac{price}{ounces}\\

This ice cream costs $4.96 for 16 ounces.

unit \ price = \frac{\$4.96}{16 \ oz}

unit \ price = \$0.31/ oz

$0.31 per ounce is less than $0.36 per ounce, so <u>Ben & Jerry's is the better buy.</u>

Answer:

Ben and Jerry's

Step-by-step explanation:

Haagen is $0.36 per oz

B&J is $0.31 per oz

Just divide price by how many oz.

For example, 4.96/16=0.31

A poll of 1,000 randomly selected registered voters was taken and 680 responded that they favor candidate X for mayor (p 1 = 0.6
Zielflug [23.3K]

Answer:

The interval (-0.0199, 0.0510) represents the region of values where the true difference (in population terms now) between the initial proportion of registered voters that favour candidate X and the proportion of registered voters that favour candidate X just before election can take on with a confidence level of 90%.

Step-by-step explanation:

Confidence Interval for the population proportion is basically an interval of range of values where the true population proportion can be found with a certain level of confidence. It is usually obtained from the sample.

p₁ represents the proportion of registered voters that favour candidate X in the initial poll, way before the election.

p₂ represents the proportion of registered voters that favour candidate X in the poll just before the election.

So, for this question the confidence interval for the true difference between the population proportion of registered voters that favour candidate X way before the elections and the population proportion that favour candidate X just before the election lies within (-0.0199, 0.0510) with a confidence interval of 90%.

Confidence interval is calculated mathematically as thus:

Confidence Interval = (Difference in Sample proportion) ± (Margin of error)

Margin of Error is the width of the confidence interval about the difference in the two sample proportions.

It is given mathematically as,

Margin of Error = (Critical value) × (standard Error)

Critical value = 1.645 (obtained from the z-tables because the sample size is large enough to ignore that information about the population standard deviation isn't given and t-critical value approximates z-critical value)

Hope this Helps!!!

Check the picture below.

let's recall that a square has all equal sides, so the perimeter of the square is about 31, and Alicia has 32 inches of trim, so she's golden.
