For which sample size (n) and sample proportion (p) can a normal curve be

Nonamiya [84]

Answer:

Option c.

Step-by-step explanation:

Using the normal curve to approximate a sampling distribution:

For a sample size n and a proportion n, the normal curve can be used if:

$np \geq 10$ and $n(1-p) \geq 10$

Option a:

$np = 35*0.8 = 28 > 10$

$n(1-p) = 35*0.2 = 7 < 10$

So option a cannot be used.

Option b:

$np = 65*0.9 = 58.5 > 10$

$n(1-p) = 65*0.1 = 6.5 < 10$

So option b cannot be used.

Option c:

$np = 65*0.8 = 52 > 10$

$n(1-p) = 65*0.2 = 13 > 10$

So option c can be used, and is the answer

Option d:

$np = 35*0.9 = 31.5 > 10$

$n(1-p) = 35*0.1 = 3.5 < 10$

So option d cannot be used.

The answer is given by option c.

What is the answer to 2x+4y=16:4y=12

allsm [11]

Answer:

Here,

$2x + 4y = 16....eqn \: i \\ 4y = 12....eqn \: ii$

substituting the value of 4y in eqn i fron eqn ii

so eqn i becomes

$2x + 12 = 16 \\ 2x = 4 \\ x = 2$

$y = 12 \div 4 = 3$

Thus,

$x = 2 \: and \: y = 3$
