Answer:
The 98% confidence interval for the true proportion of women shoppers who shop on impulse is
Step-by-step explanation:
From the question we are told that
The sample size is n = 800
The sample proportion is
Given that the confidence level is 98%
The level of significance is evaluated as
%
given that this is a two tailed test
The critical values obtained from the normal distribution table is
Now the the margin of error is mathematically evaluated as
the 98% confidence interval for the true proportion of women shoppers who shop on impulse is mathematically evaluated as
Since there are like terms, you can combine them
5a-2a = 3a
So, then you get
3a+9
Then you can factor to get a GCF of 3
3(a+3)
