At the .05 significance level, can he conclude that the number of absences has declined? Estimate the p-value.
a. State the decision rule for 0.1 significance level: H0 : μd≤ 0; H1 : μd > 0. (Round the final answer to 3 decimal places.)
Reject H0 if t > .
b. Compute the value of the test statistic. (Round the final answer to 3 decimal places.)
Value of the test statistic
c. Estimate the p-value? (Round the final answer to 4 decimal places.)
d. What is your decision regarding H0?
At the 0.05 significance level, (Click to select)do not rejectreject H0.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
