qu(16) The flavour of juicy fruit is said to last on average for 2 mins .A consumer product researcher wanted to find out if this is true and hypothesize that juicy fruit flaviour would last longer than average due to changing sticks to pellet pieces. The researcher tested 10 pieces and recorded the following data 1.45 , 1.50 , 1.45, 1.75, 2.15, 2.20 , 1.80, 1.95 , 2.05, 1.60 Test the hypotheses at the 5% level of significance. using the following Step 1: set up NULL hypotheses Step 2: set up Alternative hypothese. Step 3: choose the level signifcance and obtain Zcrt Step 4 : Calculate the zobt (using the data and z score) (sum of(x))**2 = sum(x**2) = mean = Step 5: use Zobt and Zcrt and make a desicion

The flavour of juicy fruit is said to last on average for 2 mins .A consumer product researcher
wanted to find out if this is true and hypothesize that juicy fruit flaviour would last longer than average due to changing sticks to pellet pieces. The researcher tested 10 pieces and recorded the
following data
1.45 , 1.50 , 1.45, 1.75, 2.15, 2.20 , 1.80, 1.95 , 2.05, 1.60
Test the hypotheses at the 5% level of significance. using the following
Step 1: set up NULL hypotheses
Step 2: set up Alternative hypothese.
Step 3: choose the level signifcance and obtain Zcrt
Step 4 : Calculate the zobt (using the data and z score)
(sum of(x))**2 =
sum(x**2) =
mean =
Step 5: use Zobt and Zcrt and make a desicion
