### Use the Empirical Rule to Answer Questions 1-4#### Graph Description:The graph displays a bell-shaped curve, representing a normal distribution of test scores ranging from 56 to 74. The x-axis marks specific test scores at intervals: 56, 59, 62, 65, 68, 71, and 74. This shape illustrates the distribution of scores in relation to the mean and standard deviation.#### Instruction:Use the Empirical Rule to answer the following questions.#### Questions:a. The mean is [ ].b. The standard deviation is [ ].c. [ ]% of the test scores are between 62 and 68.d. [ ]% of the test scores are between 59 and 71.e. [ ]% of the test scores are between 56 and 74.f. [ ]% of the test scores are between 65 and 68.g. [ ]% of the test scores are less than 65.h. [ ]% of the test scores are less than 68.--- Fill in the blanks using the Empirical Rule, which states that for a normal distribution:- Approximately 68% of the data falls within one standard deviation of the mean.- Approximately 95% falls within two standard deviations.- Approximately 99.7% falls within three standard deviations.

Empirical rule : An empirical rule is also known as 68 -95-99.7% rule.
