Answer:

Step-by-step explanation:

A is correct because the pizza(p) cost $6 not $2.50 and the Drinks(r) cost $2.50 not $6 so that already eliminates C and D.

And too chose between A and B is that did it need to be less than or equal too $50 (≤) .

or did it need too be more than or equal too 9p+2.5r (≥).

it needed to be less than or equal too $50 so it is ≤

Hope this helps!!

Answer:

The confidence interval is $0.2857< p < 0.4601$

Step-by-step explanation:

From the question we are told that

The sample size is n = 118

The number that gave the correct answer is k = 44

Generally the sample proportion is mathematically represented as

$\^ p = \frac{44}{118}$

=> $\^ p =0.3729$

Generally given that the confidence level is 95% the level of significance is mathematically represented as

$\alpha = (100 -95) \%$

=> $\alpha = 0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{p(1 - p)}{n} }$

=> $E = 1.96 * \sqrt{\frac{0.3729(1 - 0.3729)}{118} }$

=> $E = 0.0872$

Generally 95% confidence interval is mathematically represented as

$\r p -E < p < \r p +E$

=> $0.3729 -0.0872< p < 0.3729 +0.0872$

=> $0.2857< p < 0.4601$
