For a binomial probability distribution, it is unusual for the number of successes to be less than μ − 2.5σ or greater than μ +

ELEN [110]

Answer:

no of success deemed to be usual 5

that is more than 5 success unusual

Step-by-step explanation:

Given data

number of successes = less than μ − 2.5σ

number of successes = greater than μ + 2.5σ

trials n = 10

probability single trial = 0.2

to find out

is it unusual to have more than five successes

solution

we can say that

mean of the binomial, distribution that is

mean = probability single trial × trials n

mean = 10 × .2

mean = 2

and standard deviation = √(mean× (1-probability))

standard deviation = √2× (1-0.2))

standard deviation = 1.2649

so no of successes are

= μ − 2.5σ and = μ + 2.5σ

= 2 − 2.5(1.2649) and = 2 + 2.5(1.2649)

= -0.16225 and = 5.16225

so now we say no of success deemed to be usual 5

that is more than 5 success unusual here

Comparing with the original expression, the value that will go into the green box is 5

<h3>Exponents and indices</h3>

Given the indices expression below;

$\frac{4^{-5}}{4^4}$

Since 4^-5 is equivalent to 1/4^5, hence the given expression will be equivalent to;

$\frac{1}{4^5\times4^4}$

Comparing with the original expression, the value that will go into the green box is 5

You have been assigned to determine whether more people prefer Coke or Pepsi. Assume that roughly half the population prefers Co

Alex Ar [27]

Answer:

$n=\frac{0.5(1-0.5)}{(\frac{0.03}{1.96})^2}=1067.11$

And rounded up we have that n=1068

Step-by-step explanation:

For this case we have the following info given:

$ME=0.03$ the margin of error desired

$Conf= 0.95$ the level of confidence given

The margin of error for the proportion interval is given by this formula:

$ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}$ (a)

the critical value for 95% of confidence is $z=1.96$

We can use as estimator for the population of interest $\hat p=0.5$ . And on this case we have that $ME =\pm 0.03$ and we are interested in order to find the value of n, if we solve n from equation (a) we got:

$n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}$ (b)

And replacing into equation (b) the values from part a we got:

$n=\frac{0.5(1-0.5)}{(\frac{0.03}{1.96})^2}=1067.11$

And rounded up we have that n=1068
