In what follows use any of the following tests/procedures: regression, multiple regression, confidence intervals, one sided t-test or two sided t-test. all the procedures should be done with 5% p-value or 95% confidence interval. some answers are approximated, choose the most appropriate answer. open wages data. setup: is it true that married people have higher wages? given job is to confirm or disprove this assertion. i. what test/procedure did you perform? (6.66 points)a. one sided t-testb. two sided t-testc. regressiond. confidence intervalii. statistical interpretation? (6.66 points)a. since p-value is small we are confident that the slope is not zero. b. since p-value is small we are confident that the averages are different. c. since p-value is too large the test is inconclusive. d. none of these. iii. conclusion? (6.66 points)a. yes, we can confirm the assertion. b. no, we cannot confirm the assertion.

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
