Answer:

x = 45

Step-by-step explanation:

x and 3x are adjacent angles and the form a straight line. Their sum will be 180 degrees

x +3x = 180

Combine like terms

4x = 180

Divide each side by 4

4x/4 = 180/4

x =45

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

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

$t = 2.79$
