Kamil is saving up to buy a model of Big Ben costing £30 when he visits London. So far he has saved €15.00. How much more money
Naddika [18.5K]

Answer:

€18.40 or £16.53.

Step-by-step explanation:

Kamil is saving up to buy a model of Big Ben costing £30 when he visits London.

He has saved €15.00.

First, we have to convert his savings to Pounds(£) and then, subtract that from the amount he needs.

€1  = £0.90

€15 = 15 * 0.9 = £13.47

So, Kamil has saved  £13.47.

Therefore, the amount he has left to save is:

£30 -  £13.47 =  £16.53

To find this amount in Euros, we convert it to Euros:

£1 = €1.11

16.53 = 16.53 * 1.11 = €18.40

He has to save €18.40 or £16.53.

Construct an interval estimate for the given parameter using the given sample statistic and margin of error. For μ1-μ2, using x¯
maks197457 [2]

Answer: CI = (0, 8)

Step-by-step explanation: Confidence interval for difference between mean is given below as

Lower limit

= (x1 - x2) + margin of error

Upper limit

= (x1 - x2) - margin of error

where x1 - x2 = 8 and margin of error = 8

For lower limit,

= 8 - 8 = 0

For upper limit

= 8 + 8 = 16

Hence CI = (0, 8)
