Researchers gave 40 index cards to a waitress at an Italian restaurant in New Jersey. Before delivering the bill to each custome

rjkz [21]

The test statistic and p-value of the given data are 6.274 and 0.0001 respectively.

<h3>Test Statistic</h3>

The test statistic can be calculated using the formula below

$t = \frac{x-\mu}{\sigma / \sqrt{n} }$

Solving for the mean and standard deviation, we can substitute the values into the above equation which will be

$t = \frac{x-\mu}{\sigma / \sqrt{n} } = 6.274$

<h3>P-Value</h3>

Using the data from the test statistic, we can calculate the p-value of the data

$p-value = p(z < 6.274)= 0.0001 = 0.00$

From the calculation above, the test statistic and p-value of the given data are

6.274
0.0001

Need help with compound fractions. Please answer both

Reika [66]

$\frac{8*( \frac{c}{c} )- \frac{3}{c} }{2*( \frac{7c}{7c})+ \frac{3}{7c} } \\ \\ \frac{ \frac{8c-3}{c} }{ \frac{14c+3}{7c} } \\ \\ \frac{8c-3}{c} * \frac{7c}{14c+3} \\ \\ = \frac{56c-21}{14c+3}$

Domain restrictions are what x values make the denominator zero.
a² + 5a - 36 = (a + 9)(a - 4)
a ≠ -9 ; a ≠ 4
