If, in a sample of n = 16 selected from a normal population, X = 58 and S = 5 a. What is the value of tSTAT if you are testing the null hypothesis H0 : µ = 50?

b. How many degrees of freedom does the t test have?

c. What are the critical values of t if the level of significance, α, is 0.10 and the alternative hypothesis, H1, is µ ≠ 50?

d. What is your statistical decision if the alternative hypothesis, H1, is µ ≠ 50?

168

step-by-step explanation:

i am pretty sure that the answer is 168

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
