Use α = 0.05 to test whether the mean percentage of 17- to 24-year-olds who are attending college is the same for the four geographic regions. state the null and alternative hypotheses. h0: μn = μm = μs = μw ha: μn ≠ μm ≠ μs ≠ μw h0: μn = μm = μs = μw ha: not all the population means are equal. h0: at least two of the population means are equal. ha: at least two of the population means are different. h0: μn ≠ μm ≠ μs ≠ μw ha: μn = μm = μs = μw h0: not all the population means are equal. ha: μn = μm = μs = μw

answer: sine

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

45.36 feet per second.

step-by-step explanation:

to find the most accurate determination for the number of feet per second tyrone traveled on his way to work let us convert miles to feet and minutes to seconds.

1 mile = 5280 feet.

1 minute = 60 seconds.

now we will divide 158400 by 3492 to find the most accurate determination for the number of feet per second tyrone traveled on his way to work.

therefore, tyrone traveled on his way to work at the rate of 45.36 feet per second.
