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:
Percent = 9.6%
Step-by-step explanation:
Given the following data;
Number of suburbs = 170
Total number of suburbs = 1780
To find the percentage;
Percent = 170/1780 * 100
Percent = 17000/1780
Percent = 9.55 ≈ 9.6%
Therefore, 170 suburbs is 9.6 percent of 1780.
