Answer:
You can not divide by zero.
The inequality is equivalent to - 20.2 > 0 which is false.
Step-by-step explanation:
We can not divide both sides by zero, because if we divide both sides by zero, then the inequality becomes
⇒ - ∞ > y, which is not possible.
Again, the given inequality is - 20.2 > 0 × y.
We have to multiply y with zero and a product of zero with any term is also zero.
Hence, the inequality becomes - 20.2 > 0.
Therefore, the inequality is equivalent to - 20.2 > 0 which is false. (Answer)
Answer:
Step-by-step explanation:
Given : A new catalyst is being investigated for use in the production of a plastic chemical. Ten batches of the chemical are produced. The mean yield of the 10 batches is 72.5% and the standard deviation is 5.8%. Assume the yields are independent and approximately normally distributed.
To find : A 99% confidence interval for the mean yield when the new catalyst is used ?
Solution :
Let X be the yield of the batches.
We have given, n=10 , , s=5.8%
Since the size of the sample is small.
We will use the student's t statistic to construct a 995 confidence interval.
From the t-table with 9 degree of freedom for
The 99% confidence interval is given by,
