Craig is practicing his baseball pitching he kept track of the speed oI made a histogram at right can you tell the speed of each

LenKa [72]

Step-by-step explanation:

I am not sure, if something else is missing.

but given that one chart we can say that Craig had 2 fastest throws.

they were in the category 70-75 mph.

but we cannot say precisely which one was faster, and how fast it went.

it is also not clear what is the categorization of a border element (e.g. with an exact speed of 60 mph - is it in the 55-60 or in the 60-65 category ? or both ?).

I assume the upper limit of each interval is included, and the lower limit is excluded.

under this assumption we can say the fastest pitch was faster than 70 mph but slower than or equal to 75 mph.

How much money does the average professional hockey fan spend on food at a single hockey game? That question was posed to 10 ra

Vinil7 [7]

Answer:

Now we have everything in order to replace into formula (1):

$18-2.262\frac{2.75}{\sqrt{10}}=16.03$

$18+2.262\frac{2.75}{\sqrt{10}}=19.97$

Step-by-step explanation:

Information given

$\bar X=18$ represent the sample mean

$\mu$ population mean (variable of interest)

s=2.75 represent the sample standard deviation

n=10 represent the sample size

Confidence interval

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

The degrees of freedom are given by:

$df=n-1=10-1=9$

The Confidence is 0.90 or 90%, the significance is $\alpha=0.1$ and $\alpha/2 =0.05$ , and the critical vaue would be $t_{\alpha/2}=2.262$

Now we have everything in order to replace into formula (1):

$18-2.262\frac{2.75}{\sqrt{10}}=16.03$

$18+2.262\frac{2.75}{\sqrt{10}}=19.97$
