prisoha [69]

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

When you buy the bond the exchange rate is $1.50 = pound1. You pay pound45 ($67.50) for the British bond. You sell the bond

natka813 [3]

Answer:

The gain is of $17.50

Step-by-step explanation:

When you buy the bond the exchange rate is $1.50 = £1.

You pay £45 = $1.50\times45$ =$67.50 for the British bond.

No, you sell the bond for £50 and the exchange rate is $1.70 = £1.

So, you earned $50\times1.70=85$ dollars

Your gain is $85-67.50$ = $17.50
