Question 2 of 13, step 1 of 1 born in a large hosptal have a mean weight of 4088 grams, and a variance of 55696 128 taties are sampled at random fom the hospital what the thatthe mean wenht crthe sample babies would dner mom the population mean by less than 41 grams? Round your answer to four decimal places Answer (How to Enter Tables Keypad Hide

Explanation / Answer

here std error =(variance/n)1/2=20.86

hence probabilty that sample mean differ from population mean by less then 41 gm

=P(-41<X-4088<41)=P(-41/20.86<Z<41/20.86)=P(-1.9655<Z<1.9655)=0.9753-0.0247=0.9506
