Answer:

£210

Step-by-step explanation:

1/4 of 600= 150

2/5 of 600= 240

240 + 150= 390

600 - 390 = 210

7/20 is the fraction she has left.

1/4 + 2/5= 13/20 she has spent so she has 7/20 left.
You can also check this by adding the 150 + 240 = 390 she has spent and 210 she left to spend. 210/600 = 7/20

laila [671]

Answer: 756

Step-by-step explanation:

Given : The proportion of adults over 50 never graduated from high school. = 0.23

Margin of error : E=0.03

Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

The formula to find the sample size is given by:_

$n=p(1-p)(\dfrac{z_{\alpha/2}\ }{E})^2$

i.e. $n=(0.23)(0.77)(\dfrac{(1.96)}{0.03})^2=755.941511111approx756$

Hence, the required minimum sample size = 756
