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

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

$t = 2.79$

Victor spend a total of 33 picture and text messages which cost 8.30.if text message rate is .18 per message and the picture mes

malfutka [58]

Ok so

t=number of text messsages
p=number of picture messages

total number is 33
t+p=33

if text is 0.18 per pic and picture is 0.45 per text
total cost is 8.3
0.18t+0.45p=8.3
times 100 both sides for ease
18t+45p=830

we now have 2 equations
t+p=33
18t+45p=830

multiply first equation by -18 and add to second equation

18t+45p=830
<span>-18t-18p=-594 +</span>
0t+27p=236

27p=236
divide both sides by 27
p=8.740740740740744
this is impossible becasue you can't send 0.740740740740744 of a message so you did a mistype somewhere
