A jewelry designer claims that women have wrist breadths with a mean equal to 5 centimeters. A sample of the wrist breadths of 40 women has a mean of 5.07 centimeters. Assume that the population standard deviation is 0.33 centimeters and test the claim using a 0.05 significance level Find test statistic
Critical value
p value
and conclusion

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
