Answer:
The hypothesis test is right-tailed and the parameter that is being tested is the population standard deviation (
).
Step-by-step explanation:
We are given with the following null and alternative hypothesis below;
Null Hypothesis, 
: = 7
Alternate Hypothesis, 
: > 7
The parameter that is being tested here is the population standard deviation (). So, the null hypothesis states that the population standard deviation is equal to 7 while on the other hand, the alternate hypothesis states that the population standard deviation is greater than 7.
The above hypothesis test is right-tailed because in the alternate hypothesis, greater than sign is there which means that if the test statistics will be more than the critical value, then the null hypothesis will be rejected.
Answer:
Step-by-step explanation:
To begin simplifying this, we can first divide the coefficients, giving us:
We know that when dividing exponents, this means we need to subtract the exponent on the denominator from the numerator. This gives us:
Now, simplifying this gets:
