The hypothesis test for this claim is left-tailed.

Step-by-step explanation:

Given  : A brewery claims that the mean amount of beer in their bottles is at least 12 ounces.

Let represents the mean amount ( in ounces) of beer in any bottle.

Claim :

We know that the null hypothesis always takes equality sign, then the set of hypothesis for the given claim will be :-

Since , the alternative hypothesis is left tailed , the hypothesis test for this claim is left-tailed.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

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
