Answer:
A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 447 gram setting.

Mean = 
n = 19
Since n < 30 , so we will use t test

Substitute the values :


t calculated = -0.830
degree of freedom = n-1 = 19-1 = 18
A level of significance=α=0.025

t critical = 2.093
t calculated < t critical
So, We failed to reject null hypothesis
Decision rule -0.830< 2.093 So, We failed to reject null hypothesis
Answer:
17.5
Step-by-step explanation:
you would take 50 and multiply it by 35% or .35
Answer:
Three equivalent ratios would be 5/6, 20/24 and 30/36
Step-by-step explanation:
In order to find equivalent ratios, we need to multiply or divide both numbers by the same amount. First, lets divide both by 2.
10/2 = 5
12/2 = 6
5/6
Next we can multiply both by 2
10*2 = 20
12*2 = 24
20/24
Next we can multiply both by 3
10*3 = 30
12*3 = 36
30/36
