Question

Sample of 64 readings
from a normal population
with mean mu and variance sigma square

gave summation =5452.8
and summation (x-x)"2=973.44.
a second sample of readings from the same population gave.
vom

x=82/83/84/85/86/87
f=6 /9 /19 /27/22/17
Combine the two samples to give
estimates of u and siz and give
estimates of mu and sigma square and give the approximate 96% confidence internal
for mu​

Answer 1

Step-by-step explanation:

Sample of 64 readings

from a normal population

with mean mu and variance sigma square

gave summation =5452.8

and summation (x-x)"2=973.44.

a second sample of readings from the same population gave.

vom

x=82/83/84/85/86/87

f=6 /9 /19 /27/22/17

Combine the two samples to give

estimates of u and siz and give

estimates of mu and sigma square and give the approximate 96% confidence internal

for mu
