Answer:
Option d - Equality
Step-by-step explanation:
To find : What sign of a null hypothesis must always include?
Solution :
The Null hypothesis is defined as a statement about the population that either is believed to be true or is used to put forth an argument unless it can be shown to be incorrect beyond a reasonable doubt.
The Null hypothesis represent by 
always has a symbol with an equal in it.
Therefore, Option d is correct.
Equality sign of a null hypothesis must always include.
The answer would be 39/40.
1. Find the LCD of both of the fractions (LCD = 40)
2. Make the denominators the same as LCD (The LCD would be 40)
3. Simplify (24/40 + 15/40)
4. Join the denominators (24 + 15/40)
5. Simplify (39/40)
In decimal form its 0.975.
