Detailed explanation-1: -Explain your reasoning. Sixty-two of the 97 passengers aboard the Hindenburg airship survived its explosion. PARAMETER-the 62 surviving passengers out of 97 total passengers is a numerical description of ALL of the passengers.
Detailed explanation-2: -A parameter is a number describing a whole population (e.g., population mean), while a statistic is a number describing a sample (e.g., sample mean).
Detailed explanation-3: -A descriptive measure for an entire population is a ‘’parameter.” There are many population parameters. For example, the population size (N) is one parameter, and the mean diastolic blood pressure or the mean body weight of a population would be other parameters that relate to continuous variables.
Detailed explanation-4: -The number is a sample statistic because it describes the people in a sample, which is a subset of all of the people in the country. Sixty-four of the 93 passengers aboard an airship survived an explosion. The number is a population parameter because it is a numerical description of all of the passengers that survived.
