Answer:
The 95% confidence interval is 
The interpretation is that there is 95% confidence that the true population proportion lie within the confidence interval
Step-by-step explanation:
From the question we are told that
The sample size is n = 1003
The number that indicated television are a luxury is k = 521
Generally the sample mean is mathematically represented as
Given the confidence level is 95% then the level of significance is mathematically evaluated as
Next we obtain the critical value of 
from the normal distribution table, the value is
The margin of error is mathematically represented as
=> 
=> 
The 95% confidence interval is mathematically represented as
=> 
=>
Answer:
The statement about Rosa's calculations that is true is (0.914m)/(1yd).
Step-by-step explanation:
The ratio of meter (m) to yard (yd) is 0.914 : 1.
Therefore, the conversion factor is 0.914 m/1 yd
Answer:
1300 mm
Step-by-step explanation:
You want to convert metres to millimetres, so you multiply the metres by a conversion factor:
1.3 m × conversion factor = x mm
1 m = 1000 mm.
So, the conversion factor is either (1 m/1000 mm) or (1000 mm/1 m).
We choose the latter, because it has the desired units on top.
The calculation becomes
To answer this we just need to convert by multiplying. Lets do it:-
1 in = 2.54 cm
64 × 2.54 = 162.56
64 in = 162.56 cm.
To round 162.56 to the nearest tenth we will look at 162.56. Since this number is 5 we will round to the next number which will make it 162.60.
So, 64 in = 162.56 cm rounded to the nearest tenth is 162.60.

Answer:
$6.03
Step-by-step explanation:
The question is asking us how much each pair of socks cost. With the information we are given, we know that there are 5 pairs and that they all cost the same amount. If the total were just the 5 socks, we could easily divide the total by 5 to get the price of each pair but that's not the case. The soccer ball is included in the final cost. To overcome this, we just have to subtract the soccer ball's cost ($45) from the total.
So we subtract $45 from $75.15, giving us $30.15, the total amount of all the socks. However we need to find out how much each pair costs and there are 5 of them, so we divide 30.15 by 5. This gives us the answer, $6.03.
Each pair of socks cost $6.03.
Simpler Explanation:
- $75.15 - $45 = $30.15
- $30.15 / 5 = $6.03
The answer is $6.03
