Answer to Problem 37SGA

  [0.975,2.625]

Explanation of Solution

Given:

The average hours of cleaning the home is 1.8 with a standard deviation of 0.5 in a random sample of 200 adults.

Calculation:

Given that -

  σ=0.5,N=200,X¯=1.8

It is also given that P=90% .

Now, P=90% correspond to t=1.65 using page number 919.

Now, finally let us find the range about the mean as follows-

  [X¯tσ,X¯+tσ]=[1.81.65×0.5,1.8+1.65×0.5]=[0.975,2.625]
