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

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

$t = 2.79$

The fraction models below represent two fractions of the same whole. How much of the Fraction 5 over 8 is in the Fraction 1 over

IrinaVladis [17]

To find how much of 5/8 is you would need to divide 1/2 by 5/8:

X = (1/2) / (5/8)

When dividing fractions, you reverse the second fraction and multiply:

X = (1/2) x (8/5)

X = 8/10

Simplify:

X = 4/5
