Answer:

Step-by-step explanation:

Hypotheses:

H_0: p=0.39\\H_a:p

(Left tailed test)

p = sample proportion

n = sample size = 200

Sample proportion = p = 73/200 = 0.365

Std error = 0.03404

p difference = 0.365-0.39 = 0.025

t = 0.025/se = 0.7344

df = 199

p value = 0.2317

Since p >0.05 accept null hypothesis

No,the veterinarian does not have a right to be​ skeptical because there is no statistical evidence to support his claim.

Solve for x if 2(5x+2)^2=48
likoan [24]
2(5x + 2)^2 = 48
divide both sides by 2
(5x + 2)^2 = 24
square root both sides to clear the power of two.
5x + 2 = + - sqrt24
subtract 2 from both sides
5x = -2 + - sqrt 24
divide both sides by 5
x = (-2 +-sqrt24)/5 or decimal answers .58 and -1.38
