Answer: 3/8, 0.375, 37.5%

Step-by-step explanation:

Count the number of cards with odd numbers that are greater than 4. 5, 7, and 9 are odd numbers greater than 4. There are 3 cards with odd numbers greater than 4. Probability is found by dividing this by the total number of cards, 8. This gets you a fraction of 3/8.

You can use a graphing paper or a software to create a scatter plot. I used MS Excel to plot the points. You simply have to type the values and create a graph. The x-axis is the number of years and the y-axis is the savings account balance.

A random sample of 28 fields of spring wheat has a mean yield of 44.7 bushels per acre and standard deviation of 6.96 bushels pe

Bingel [31]

Answer:

$44.7-2.052\frac{6.96}{\sqrt{28}}=42.001$

$44.7+2.052\frac{6.96}{\sqrt{28}}=47.399$

And the confidence interval would be between 42.001 and 47.399

Step-by-step explanation:

Information given

$\bar X=44.7$ represent the sample mean for the sample

$\mu$ population mean

s=6.96 represent the sample standard deviation

n=28 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:

$df=n-1=28-1=27$

The Confidence interval is 0.95 or 95%, the significance is $\alpha=0.05$ and $\alpha/2 =0.025$ ,the critical value for this case would be $t_{\alpha/2}=2.052$

And replacing we got:

$44.7-2.052\frac{6.96}{\sqrt{28}}=42.001$

$44.7+2.052\frac{6.96}{\sqrt{28}}=47.399$

And the confidence interval would be between 42.001 and 47.399
