PLEASE HURRY WILL GIVE U POINTS OR WHATEVER IT IS 1. A simple random sample of size n = 46 is drawn from a population whose population
standard deviation is o = 3.7. The sample mean, , is determined to be 57.6. Construct a
96% confidence interval for u. Express the z-score to three decimals. Round the
endpoints of the interval to one decimal. (Z-interval)

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

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

it is x=-4
