Answer:
1/4
Step-by-step explanation:
When rolling two dice there are 36 possible outcomes
The results that would fit the outcome of 2 even numbers
(2,2)(2,4)(2,6)(4,2)(4,4)(4,6)(6,2)(6,4)(6,6).
P ( even, even) = (number of even, even outcomes)/ total
= 9/ 36
=1/4
Answer:
3/5
Step-by-step explanation:
The probability of an even number coming 6 times out of 10 is 6/10. Simplify to get 3/5
The answer is B. -4
You can simply count the blocks
So for every one block over on the x-axis it goes 4 blocks down on the y axis
0.578 rounded to the nearest tenth would be 0.6, since the 7 in the hundredths spot is higher than 5.
Answer:
Step-by-step explanation:
The type I error occurs when the researchers rejects the null hypothesis when it is actually true.
The type II error occurs when the researchers fails to reject the null hypothesis when it is not true.
Null hypothesis: The proportion of people who write with their left hand is equal to 0.23: p =0.23
Type I error would be: Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually different from 0.29
Since 0.29 is assumed to be the alternative claim.
Type II error would be: Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29
Still with the assumption that 0.29 is the alternative claim.
