Yakvenalex [24]
In this situation, you have:
The mode is 79 (that’s the most common number).
The median is 78.5 (the middle value or the average of the two middle values, since there is an even number of test scores).
The mean is less than both of those, as it was brought down by the few scores of 49.

The means the mean will be less than median.

Answer:

The test statistic is t = 2.79

Step-by-step explanation:

From the question we are told that

    The population mean is \mu   = 59.3

    The sample size is  n  =  79

    The  sample mean is  \= x  = 62.4

    The  standard deviation is  \sigma  =  9.86

Generally the test statistics is mathematically represented as

            t =  \frac{\= x - \mu }{ \frac{ \sigma}{ \sqrt{n} } }

substituting values

          t =  \frac{ 62.2 -  59.3 }{ \frac{  9.86}{ \sqrt{ 79} } }

          t = 2.79
