Hii! I really need help on this with the spree that answers! For 30 points. I don’t wanna waste my points so make sure your answ
yarga [219]

Step-by-step explanation:

1. K = 13 (13+5=18)

2. X= 36 (36-12=24)

3. Y = 14 (17=3+14)

4. Z= 24(22=24-2)

5. A=7 (divide both sides by 4)

6. H=12 (12/6=2)

7. B= 10 (100=10*10)

8. Y=42 (6=42/7)

I'm pretty sure that this is correct.

An inspector inspects a shipment of medications to determine the efficacy in terms of the proportion p in the shipment that fail
Dafna1 [17]

Solution :

It is given that :

$H_0:p \geq 0.05$     (Null hypothesis, $H_0 : p = 0.05$ is also correct)

$H_a:p     (Alternate hypothesis, also called $H_1$)

This is a lower tailed test,

Therefore,

Sample proportion, $\hat p = \frac{x}{n}$

                                    $=\frac{8}{200}$

                                    = 0.04

And claimed proportion, P = 0.05

Significance level, $\alpha$ = 0.01

Therefore, calculating the statistics, we get

Standard deviation of $\hat p, \sigma_{\hat p}=\sqrt{\frac{P\times (1-P)}{n}}$

                                             $=\sqrt{\frac{0.05\times (1-0.05)}{200}}$

                                               $\approx 0.0154$

Test statistic,

$z_{observed}=\frac{\hat p -0.05}{\sigma_{\hat p}}$

              $=\frac{0.04 -0.05}{0.0154}$

               $\approx -0.65$

Now since this is a lower tailed test, p-value = $P(Z < z_{observed})=P(Z < -0.65)=0.2578$

Rejection Criteria : Reject $H_0$ if p-value < α .

Conclusion : Since the p-value $\geq \alpha$, we fail to reject the null hypothesis. There is insufficient evidence that p is less than 0.05
