A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 410 gram setting. It is believed that the machine is underfilling or overfilling the bags. A 15 bag sample had a mean of 405 grams with a variance of 169. Assume the population is normally distributed. Is there sufficient evidence at the 0.05 level that the bags are underfilled or overfilled

need points to ask question

step-by-step explanation:

x/3-10=8

x/3=18

x=48

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

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
