Answer:
b). Reject the null hypothesis and conclude the means are different.
Step-by-step explanation:
A hypothesis is characterized as null when the data/statistics display that there is no distinction between the particular features of the groups. As per the details provided, the decision would be to 'reject/deny the null hypothesis and deduce that the means of the processes are different.' This <u>shows that there is no association among the variables due to the distinction in the means of the two processes and other data provided</u>. Thus, <u>option b</u> is the correct answer.
Given :
12 foot tall street light is making a 18 foot shadow at the same time a nearby building is making a 72 feet shadow.
To Find :
How tall is the building.
Solution :
Since, the time period is same so the angle angle of elevation is equal i.e the ratio of height of building is equal to height of shadow.
Let, height of building is h feet.
So,
Therefore, height of building is 48 feet.
Hence, this is the required solution.

Answer:
Z> 4
So Z> 2 is true
Step-by-step explanation:

Adding 2 on both sides
Z-2 + 2 >2 + 2
Z > 4
hence the equation Z > 2 is true
