Answer: 1/3
Step-by-step explanation:
Number of red marbles = 5
Number of blue marbles = 9
Number of yellow marbles = 8
Number of and black marbles = 6
Total number of marbles = 28
If Taylor pulled out a yellow one and didn't replce it, there'll be 27 marbles left since one has been removed, then the probability of picking blue marbles will be:
= Number of blue marbles / Total marbles
= 9 / 27
= 1/3
The probability of picking a blue marble is 1/3.
Answer:
<h2>In this case,the answer would be option d) given in the answer choices or options or A two-sample t-test for a difference between population means.</h2>
Step-by-step explanation:
- In Statistics,a two sample test is generally used to examine or compare two different population means with the main objective to verify whether the population means are equal or otherwise.
- The two sample t-test basically involves the hypothesis testing to determine or verify the equality between two concerned population means.
- In this case,the two different populations of raccoons are given and the equality of the mean sample weights of the two distinct populations can be determined or evaluated by employing the hypothesis testing method under a two sample t test for measuring difference in two population means.
Answer:
1. 180
2. 300
3. 480
Step-by-step explanation:
1. Since 30% of 600 (or 0.3 * 600) = 180, the 1st blank is 180.
2. 50% of 600 (also easy to just think of one half {1/2}) = 300
3. Because 180 + 300 = 480
hope this helps:)
1] 0.23
2] both are same
3] 20/100 *80= 16
