*This is on the assumption that the equation is
So firstly, you'll need to rewrite this as
Next, remember the rule for exponents to radicals: " . Applying this rule to both would look like this:
Next, simplify 2^3:
Next, apply the product rule of radicals (√ab = √a*√b) to this expression, and your answer will be
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
