Final answer:
To check if two values are not equal, use the inequality operator (!=), which returns true if the values are not equal and false if they are equal.
Correct option is A
Step-by-step explanation:
To check if value1 is not equal to value2, you use the inequality operator (!=). This operator compares the two values and returns true if they are not equal and false if they are equal. For example, in the statement if (a != b), the code inside the if block will execute only if a is not equal to b.
When writing the alternative hypothesis in statistics, which is typically denoted with H or H₁, you use symbols like not equals (‡), less than (<), or greater than (>). For instance, if you are testing whether a certain parameter is different from a hypothesized value, you might write H₁: µ ‡ value.
