Answer: The test statistic is t= -0.90.
Step-by-step explanation:
Since we have given that
n₁ = 50
n₂ = 25
So, s would be
So, the value of test statistic would be
Hence, the test statistic is t= -0.90.
Answer:
0.5
Step-by-step explanation:
This is an example of mutually exclusive event in which two or more events cannot occur at the same time or in a single performance.
Therefore, the probability the number of cars entering the roadway is between 4 and 6 cars per minute (inclusive) implies that it is either 4, 5 or 6 cars enter in a minute. Since we have an average of 6 cars per minute, the probability of each of the event occurring is 1/6. This can therefore be calculated as follows:
P(4 or 5 or 6) = (1/6) + (1/6) + (1/6)
= 3/6
= 1/2
= 0.5
Therefore, the probability the number of cars entering the roadway is between 4 and 6 cars per minute (inclusive) is 0.5.
Answer:
The answer could be anything below - 7 degrees Fahrenheit, so
-9 degrees Fahrenheit
Answer:
A
Step-by-step explanation:
g(x)=f(x)+6
This is a change in range.
The graph of g(x) is obtained by shifting the graph of f(x) 6 units upwards
