question 49

Multiple Choice

Which of the following statements is true?

• A) A class with multiple base classes can inherit constructors from any of its base classes.
• B) If a class inherits constructors with the same signature from two or more base classes, then the derived class must define its own version of that constructor; otherwise, a compilation error occurs.
• C) When a derived class is inheriting constructors from a base class and explicitly defines a constructor, if a default constructor is needed, the derived class must define a default constructor either by using = default to tell the compiler to generate the default constructor or by explicitly defining a constructor that can be called with no arguments.
• D) All of the above.

Definitions:

P-Value

The probability of obtaining test results at least as extreme as the results actually observed, assuming that the null hypothesis is true.

Significance Level

The threshold against which the p-value is judged to determine statistical significance, often denoted by alpha (α) and commonly set at 0.05 or 5%.

Significance Level

A threshold or probability used in statistical hypothesis testing to determine whether to reject the null hypothesis, often denoted by alpha with a common value of 0.05.

Z-statistic

A statistic that measures the distance in standard deviations of a sample mean from the population mean under the null hypothesis.
