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

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

$t = 2.79$

Nuetrik [128]

Answer:

$14.64

Step-by-step explanation:

First, find how much he spent on the calculators

So, he spent 7.36 on each student so far.

To find how much he still has left to spend, subtract the amount he has spent from the total he can spend

total-$ spent on calculators

22-7.36=14.64

He can still spend $14.64 on each student

Hope this helps! :)
