Answer:
5y/x
Step-by-step explanation:
this is all i can write as an equation boo
It would be the same you would already be dividing by 3 because it’s the denominator and the numerator is 2
Answer:
Less then
Step-by-step explanation:
When you dived by a decimal the answer decreases.
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,




Yes, 8 is a solution to the equation
