Answer:
the answer would be 1/15, or approximately 0.067.
Step-by-step explanation:
Answer:
4.84% of trees on the island are poisonous.
Step-by-step explanation:
The proportion of fruit trees that are poisonous is the number of poisonous fruit trees divided by the total number of trees.
The percentage is the proportion multiplied by 100.
In this question:
60 poisonous trees.
1240 total trees.
60/1240 = 0.0484
0.0484*100 = 4.84%
4.84% of trees on the island are poisonous.
40 flights if you're asking how many flights happen in 1 hour.
Answer:
The second equation in attached picture
Step-by-step explanation:
Since the slope of the given line is 3/2, then you take the negative reciprocal, which is -2/3. So the second equation in your attached picture is correct.
As the level of significance here is 0.05 because we are comparing the p-value with 0.05. Therefore the critical region boundaries here would be given as:
For 5 degrees of freedom, we get: ( from the t-distribution tables )
P(t_5 < 2.571) = 0.975
Therefore due to symmetry, we get:
P(-2.571 < t_5 < 2.571) = 0.95
Therefore the critical region here would be given as: +2.571 and -2.571
