Answer:
The probability that the sample mean would differ from the population mean by greater than 2.2 kilograms is 0.0104 .
Step-by-step explanation:
The mean weight of an adult is 62 kilograms with a variance of 144
i.e.
We are supposed to find probability that the sample mean would differ from the population mean by greater than 2.2 kilograms
i.e.
Using formula :
Refer the z table
Hence The probability that the sample mean would differ from the population mean by greater than 2.2 kilograms is 0.0104 .
