One variable examined is the survival rate 10 years after tagging. The scientists observed that 10 of the 50 metal tagged pengui

Oksana_A [137]

Answer: 90% confidence interval would be $(-0.2483,-0.0717)$

Step-by-step explanation:

Since we have given that

n₁ = 50

Number of metal tagged penguins survived = 10

So, $p_m=\dfrac{10}{50}=0.2$

n₂ = 50

Number of electronic tagged penguins = 18

So, $p_e=\dfrac{18}{50}=0.36$

So, at 90% confidence interval, z = 1.28

So, interval would be

$(p_m-p_e)\pm z\sqrt{\dfrac{p_m(1-p_m)}{n}+\dfrac{p_e(1-p_e)}{n}}\\\\=(0.2-0.36)\pm 1.28\sqrt{\dfrac{0.2\times 0.8}{50}+\dfrac{0.36\times 0.64}{50}}\\\\=-0.16\pm 0.0883\\\\=(-0.16-0.0883,-0.16+0.0883)\\\\=(-0.2483,-0.0717)$

Hence, 90% confidence interval would be

$(-0.2483,-0.0717)$

Becca and alice are training for a race. becca runs 3 3/4 miles in 1/2 of an hour, and alice runs 5 1/4 miles in 3/4 of an hour.

Drupady [299]

Becca: in 1 hour;

(3(3/4) miles in 1/2 hour)2
=7.5 miles in 1 hour

Alice: in 1 hour;

(5(1/4) miles in 3/4 hours)
She travels 5(1/4)/3 = 1.75 miles in 1/4 hours.

Travels 1.75x4 = 7 miles in 1 hour

As seen, Becca runs faster, 0.5 miles per hour faster.

Hope I helped :)
