A test was made of H0: μ1 = μ2 versus H1: μ1 < μ2. The sample means were x1-bar = 11 and x2-bar = 9, the sample standard deviations were s1 = 7 and s2 = 5, and the sample sizes were n1 = 15 and n2 = 13. Is H0 rejected at the 0.05 level? (Hint: First compute the value of the test statistic.)

Yes or No

12*c

step-by-step explanation:

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
