Answer:
Step-by-step explanation:
Hypotheses:

(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.
Answer:
1/3
Step-by-step explanation:
Of the numbers between 1 and 12, the numbers that are multiples of 4 or 6 are: 4, 6, 8, 12.
So the probability is 4/12, or 1/3.
Answer:
y = x + 1 y = -x + 21
(0, 1) (0, 21)
(1, 2) (1, 20)
(2, 3) (2, 19)
(3, 4) (3, 18)
Step-by-step explanation:
76,500/100,000 divide by 100
765/1,000. divide by 5
153/500
Answer:24,942,060
Step-by-step explanation:
(10,10,4) - (3,2,0) = 7,8,4
7+8+4=19
19!/(7!*8!*4!)= 24'942'060
