Answer:
8/25
Step-by-step explanation:
125 marbles total
15 green marbles + 25 blue marbles = 40
40/125 simplified to simplest form is 8/25
Answer:
1. 80%.
2. 2 quarters, 3 dimes, 4 nickels, 30 pennies. (if you don't use pennies make it 6 dimes.)
Answer:
P(milk) = 7/18
P(not milk) = 11/18
Step-by-step explanation:
The bag contains 7 milk and 11 dark chocolates. That means that there are a total of; 7 + 11 = 18 sweets in the bag.
So, when a sweet is selected at random, probability that the sweet is milk is;
P(milk) = number of milk sweets/total number of sweets = 7/18
Probability it is not milk is;
P(not milk) = number that's not milk/total number of sweets = 11/18
B...
|-24+6|=18
Same for the other one.
Answer:
When all possible differences between pairs of population means are evaluated not with an F test, but with a series of regular t tests, the probability of at least one:
A. type I error is larger than the specified level of significance.
B. type II error is larger than the specified level of significance.
C. type I error is smaller than the specified level of significance.
D. type II error is smaller than the specified level of significance.
Answer : Type I error is larger than the specified level of significance.( A )
Step-by-step explanation:
An F test is a test that is used to test whether the variances between pairs of populations are equal while a T test is a test used to check if a pair of population are equal not considering the fact that the variances of the population are different .
When a T test is used to evaluate all possible differences between pairs of population instead of F test there is a probability of atleast one type 1 error larger than the specified level of significance.
