A manufacturer claims that the thickness of the spearmint gum it produces is 7.5 one-hundredths of an inch. A quality control specialist regularly checks this claim. On one production run, he took a random sample ofn= 10 pieces of gum and measured their thickness. He obtained the following scores:
7.65
7.60
7.65
7.70
7.55
7.55
7.40
7.40
7.50
7.50
The quality control specialist's hypotheses are:
H0:= 7.5
HA: 7.5
The quality control specialist entered his data into Minitab and requested that the "one-samplet-test" be conducted for the above hypotheses and=0.05. What was his output?A manufacturer claims that the thickness of the spearmint gum it produces is 7.5 one-hundredths of an inch. A quality control specialist regularly checks this claim.
