Answer:
Hello your question has some missing information below is the missing information
Sample mean and Sample standard deviation
Bass 70.99 and 2.52
Tenor 69.41 and 2.79
answer : <em>We will reject H0 </em>
Step-by-step explanation:
<u>Determine whether the population mean height of bass singers > population mean height of tenor singers </u>
n1 = 64 , n2 = 42
x1 ( mean ) = 70.99
x2( mean ) = 69.41
S1 ( std 1 ) = 2.52
S2 ( std 2 ) = 2.79
We will perform a two tailed test hence we will state the null and alternate hypothesis
H0 : μ1 > μ2
H1 : μ1 < μ2
significance level = 0.01
next calculate the test statistic
t = 2.96
attached below is the remaining part of the detailed solution

The median is the middle number when the numbers are in ascending or descending order.
In this case, the numbers are already in ascending order.
There is an even number of numbers, so we need to find the two middle numbers.

Now, find the average of these numbers by adding them together and dividing them by
, which is the number of values.

My answer was 56/27. Here is the work I did.
Answer:
Step-by-step explanation:
-(-1) is 1 because if you multiply by a negative number becomes positive
so
it is 1 unit to the right of 0
