In order to test the mean iq of employees in an organization is greater than 100, a sample of 30 employees is taken and the value of the test statistic is computed as t29 = 2.42. if we choose a 5% significance level, we

a. reject the null hypothesis and conclude that the mean iq is greater than 100.

b. reject the null hypothesis and conclude that the mean iq is not greater than 100.

c. do not reject the null hypothesis and conclude that the mean iq is greater than 100.

d. do not reject the null hypothesis and conclude that the mean iq is not greater than 100.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8
