You conduct a statistical test of hypotheses and find that the null hypothesis is statistically significant at level α = 0.05. You may conclude that

A. the test would also be significant at level α = 0.10.

B. the test would also be significant at level α = 0.01.

C. both options one and two are true.

D. neither options one or two is true.

Neither options one or two is true

Step-by-step explanation:

When we test a statistical hypothesis, we must specify a level of significance. It is this level of significance that presents the maximum probability at which we are willing to risk committing a type one error.

Therefore, it is independent of any other level of significance used.

Hence, we conclude that neither options one or two is true.

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.
