Question

What is the 97% confidence interval for a sample of 104 soda cans that have a mean amount of 15.10 ounces and a population standard deviation of 0.08 ounces?

Answer 1

{15.083, 15.117}

Explanation:

`\displaystyle CI_(97\%)=15.10\pm2.17\biggr((0.08)/(√(104))\biggr)\approx\{15.083,15.117\}`

Note that the critical value for a 97% confidence level is
`z=2.17`
