If a rectangular prism is sliced vertically by a plane, what is the shape of the resulting two dimensional figure?

The 95% confidence interval estimate of the true population proportion of U.S. employers that were likely to require higher employee contributions for health care coverage is 0.52 +/- 0.0370

= (0.4830, 0.5570)

The margin of error M.E = 0.0370

Step-by-step explanation:

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

p+/-z√(p(1-p)/n)

p+/-M.E

Given that;

M.E = margin of error

Proportion p = 52% = 0.52

Number of samples n = 700

Confidence interval = 95%

z value (at 95% confidence) = 1.96

Substituting the values we have;

0.52 +/- 1.96√(0.52(1-0.52)/700)

0.52 +/- 1.96(0.0189)

0.52 +/- 0.0370

( 0.4830, 0.5570)

The 95% confidence interval estimate of the true population proportion of U.S. employers that were likely to require higher employee contributions for health care coverage is 0.52 +/- 0.0370

= (0.4830, 0.5570)

The margin of error M.E = 0.0370

A new television set was recently purchased for the common room in a Residence Hall for $428.00 including tax. If the tax rate i

prohojiy [21]

The price of the television set before taxes is $400

<h3>How to find the price of the television set before taxes.?</h3>

The given parameters are:

Price after tax = $428.00

Tax rate = 7%

The price of the television set before taxes is calculated as:

Price after tax = Price before tax * (1 + tax rate)

This gives

$428.00 = Price before tax * (1 + 7%)

Express the percentage as decimal

$428.00 = Price before tax * (1 + 0.07)

Evaluate the sum

$428.00 = Price before tax * (1.07)

Divide both sides by 1.07

Price before tax = $400

Hence, the price of the television set before taxes is $400
