The distribution of sample means for monthly employee income at a particular company for samples of 70 employees is normal, with a mean of $5971 and a standard deviation of $219 . You take a random sample of 70 employees from the company and find that their mean monthly income is $5 comma 751 . How many standard deviations is the sample mean from the mean of the distribution of sample means? Round to one decimal place.

The value is  

Step-by-step explanation:

From the question we are told that

    The sample size is  n =  70  

    The mean is  

    The standard deviation is  

     The sample mean is  

Generally the number of standard deviations the sample mean is from the mean of the distribution is mathematically represented as

=>      

=>          

=>          

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
