Answer: b. The 99% interval is longer.
Step-by-step explanation:
The formula to find the confidence interval for mean :
, where is the sample mean , is the population standard deviation , n is the sample size and is the two-tailed test value for z.
For 95% confidence interval the two-tailed test value for z is .
For 99% confidence interval the two-tailed test value for z is .
Since the interval is directly proportion al to the z-value , so it is clear that the width of the interval would be longer with z =3 than z=2.
i.e. The <u>99% interval</u> is longer than 95% confidence interval .
If an employee has already measured out 59 pounds of wild rice. The number of pounds of long grain brown rice should she add to make the blend is: 88.5 pounds of long grain.
<h3>
Number of pounds of long grain</h3>
Let x represent number of pounds of long grain
6.45×59+3.95x=(59+x)×4.95
380.55+3.95x =292.05+4.95x
380.55–x =292.05
-x=292.05-380.55
-x = -88.5
x = 88.5 pounds of long grain
OR
6.45×59+3.95x=(59+x)×4.95
x=(6.45-4.95)×59
x=1.5×59
x=88.5 pounds of long grain
Therefore If an employee has already measured out 59 pounds of wild rice. The number of pounds of long grain brown rice should she add to make the blend is: 88.5 pounds of long grain.
