Health insurance benefits vary by the size of the company. The sample data below show the number of companies providing health i
telo118 [61]

Answer:

Step-by-step explanation:

a. The hypothesis of testing are

Null Hypothesis, H0: The health insurance coverage is independent of the size of the company.

Alternative hypothesis, H1: The health insurance coverage is not independent of the size of the company

The test statistics is calculated as

X² =  <u>∑(Ei - Oi)²</u>  ≅X²(r-1)(c-1)

        i      Ei

where Oi's are the observed values and Ei's are the expected values,

E= <u>row total × column total</u>

            total

The expected values are

        Sizeof the Company  

Health Insurance    Small   Medium Large Total

Yes                             42     63          84           189

No                              8             12          16           36

Total                      50    75                  100           225

Therefore, the test statistics is

X² =∑ (<u>Ei -Oi)² </u>=6.94 ≅  x²₂

      i       Ei

The critical value is found to be 5.99. Since test statistics > critical value, we reject H0 and conclude that the health insurance coverage is not independent of the size of the company.

The associated p-value is 0.031 (<0.05).

b. Percentage of employees lacking health insurance coverage is

Small 14/50 x 100 = 28%

Medium 10/75 x 100 = 13%

Large 12/100 x 100 = 12%

Hence depending on the above percentage, we can support the claim that the employees of small companies are more likely to lack health insurance coverage.

A printing business employs 35 people. The employer offers the employees an insurance package that costs the company $2,170. The
7nadin3 [17]

Answer:

New plan better

Step-by-step explanation:

We need to compare the cost of the first plan, $2170, to the cost of this  new plan. Fot this, we need to find the cost of the new plan. We need an equation for this.

For the new plan there is a fixed cost of $70, i.e, no matter how many employees there will be, the firm would have to pay $70. Then, if it has 1 employee, would face a cost of $70 + $59, where this $59 is the cost per employee. If the firm has 2 employees the cost will be $70 + $59 + $59 = $70 + 2*($59). If it hires 3 employees: $70 + $59 +$59 +$59 = $70 + 3*($59). And so forth for 4, 5, 6 employees.

Then, for the 35 employees the firm has the cost is:

$70 + 35*($59) = $2135

As $2135 < $2170, this new plan is better
