Mathematics

Confidence interval decreases, error decreases

Option: a

<u>Explanation:</u>

Increasing of sample size will decrease the width of the confidence intervals because it also decreases the standard error of the interval. So whenever the 'sample size' is increases then the 'confidence interval' decreases as well as the 'error' decreases.

Confidence interval gives us the unknown average population or percentage of the population. This gives us just how much the average rate is varying. Confidence interval gives the location as well as the precision of a measure. The smaller sample sizes gives more wider intervals.

Which inequality is equivalent to -m ≥ 15?
Vera_Pavlovna [14]

Answer:

m ≤ -15

Step-by-step explanation:

You can convert m into positive by multiplying -1 on both sides of the equation. This would also result to a -15.

Note that when an unknown variable changes its sign, the symbol becomes the opposite version of itself.

So,

-m ≥ 15

-m(-1) ≥ 15(-1)

m ≤ -15

Chicken costs $3.20 per pound, and beef costs $4.59 per pound. How much more does 3 pounds of beef cost than 3 pound of chicken?
tensa zangetsu [6.8K]

To find the difference, first calculate how much 3 pounds of each meat costs.

$3.20 × 3 = $9.60 for 3 pounds of chicken

$4.59 × 3 = $13.77 for 3 pounds of beef

Now, take the difference.

$13.77 - $9.60 = $4.17

<h3>Answer:</h3>

3 pounds of beef costs $4.17 more than 3 pounds of chicken.
