Answer:

$B = \frac{3}{2} * 21,356$

Step-by-step explanation:

Given

Represent Jimmy with J and Bob with B

$J = 21,356$

$B = 1\frac{1}{2} * J$

Required

Determine the expression for B

$B = 1\frac{1}{2} * J$

Substitute 21,356 for J

$B = 1\frac{1}{2} * 21,356$

Convert Mixed fraction to improper

$B = \frac{3}{2} * 21,356$

The above is an expression for B

Solving further, we have

$B = \frac{3 * 21,356}{2}$

$B = \frac{64068}{2}$

$B = 32034$

Answer:

1568

Step-by-step explanation:

The computation of the minimum sample size is shown below:

Given that

Error E = 11

The population standard deviation $\sigma$ =217

Confidence level 1-α = 95%

Now following formula should be used

n > (Zalpha ÷ 2 × sigma ÷ E)^2

As we know that

Zalpha ÷ 2= 1.96

Now the sample size is

n> (1.96 × 202 ÷ 10)^2

= 1568
