10.A noted psychic was tested for ESP. The psychic was presented with 200 cards face down and askedto determine if the card was
lions [1.4K]

Answer:

Step-by-step explanation:

The sample proportion \hat p = \dfrac{50}{200}

\hat p = 0.25

The null hypothesis and the alternative hypothesis:

H_o: p = 0.20  \\ \\  H_1 : p > 0.20

Thus; the test statistics is:

Z = \dfrac{\hat p - p_o}{\dfrac{p_o(1-p_o)}{n} }

Z = \dfrac{0.25 -0.20}{\sqrt{\dfrac{0.20(1-0.20)}{200} }}

Z = \dfrac{0.05}{\sqrt{\dfrac{0.16}{200} }}

Z = \dfrac{0.05}{\sqrt{0.0008 }}

Z = 1.768

P-value = 2 × P(Z< - 1.768)

From the z tables

P-value = 2 × 0.03853

P-value = 0.07706

Thus, the p-value is 0.05 < P-value < 0.10

Pls help. Just need the formula to enter into the "y=" slot. Thank you :)
professor190 [17]

Answer:

I believe its y=7^{2}

My thinking:

I think when the slope intercepts the Y line is when it’s called the y-intercepts and that’s basically how got my answer.

Please do correct me if I’m wrong

It’s been a while since I done something like that ( it hasn’t been that long actually, I just forgot a lot of it)

Sorry if I’m wrong, I hope that I at least helped a Little
