Question

Mohan caught 100 frogs from a garden and measured their weights. The mean weight of these frogs is a :

• A. parameter
• B. central limit
• C. statistic
• D. null hypothesis

Answer 1

The Correct Option is C

Mohan captured and assessed the weights of 100 frogs, and computed their mean weight. This activity includes data collection from a sample because not all frogs from the entire population were measured.

In statistics, a statistic is a characteristic or measure obtained by using the data values from a sample. Since the mean weight was derived from Mohan's sample of 100 frogs, it is considered a statistic, not a parameter. A parameter, in contrast, is a measure obtained from the entire population.

Therefore, among the options given:

parameter

central limit

statistic

null hypothesis

The correct choice is "statistic", as it matches the description of what was calculated from the frog sample.
