In a population of subjects who died from lung cancer following exposure to asbestos, it was found that the mean number of years elapsing between exposure and death was 25. The standard deviation was 7 years. Consider the sampling distribution of sample means based on samples of size 35 drawn from this population. Required:
What will be the standard deviation of the sampling distribution?

The value is  

Step-by-step explanation:

From the question we are told that

   The  population mean is

    The population standard deviation is  

    The sample size is  n =  35

Generally the standard deviation of the sampling distribution is mathematically represented as

=>    

=>    

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

you can't solve x because it is 2 linear equation and you only have one equation
