-25 15/19 + 9/1

get a common denominator of 19

they multiplied 9/1 * 19/19 = 171/19

-25 15/19 + 171/19 =

change the mixed number to an improper fraction

(19* 25 +15)/19 = 490/19

-490/19 + 171/19 =

add together

-319/19

now convert the improper fraction back to a mixed number

19* 16 =304 319-304=15

-319/19 =-16 15/19

Suppose the number of free throws in a basketball game by one player are normally distributed with a standard deviation 0.97 fre

babunello [35]

Answer: 1.960

Step-by-step explanation:

The value of z we use to calculate a confidence interval with a ( $1-\alpha$ ) confidence level is a two-tailed test value i.e. represented by :-

$z_{\alpha/2}$

Given : The level of confidence: $1-\alpha=0.95$

Then, significance level : $\alpha: 1-0.95=0.05$

With the help of standard normal distribution table for z , we have

$z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.960$

Hence, the value of z should be used to calculate a confidence interval with a 95% confidence level =1.960
