Question 347150: Facts:
Random sample of 44
Standard deviation of 2.4
Point estimate of 7.59
Obtain an approximate 95.44% confidence interval for the mean number of young.
This is my response 2*2.4=4.8 x-4.8 = 7.59-4.8 = 2.79 x+4.8=7.59+4.8=12.39, so 95.44% certain between 2.79 and 12.39.
Can you please tell me if I have done this correct. Thank you for all of your help.

Facts:
Random sample of 44
Standard deviation of 2.4
Point estimate of 7.59
Obtain an approximate 95.44% confidence interval for the mean number of young.
-------------
1.00-0.9544 =
x-bar: 7.59
E = [-invT(0.0228,43]*2.4/sqrt(44) = 0.7449
--------
95.44% CI: 7.59-0.7449 < u < 7.59+0.7449
---
95.44% CI: 6.8451 < u < 8.3349
