Answer:

The second graph from the top left side.

Step-by-step explanation:

When the data 8, 9, 10, 11, 11, 14, 18, 28, 28, 29, 40, 41, 41, 44, 45, 47, 55 is drawn in histogram.

Then in first interval 0 - 9 there are two numbers ( 8, 9 ) so, this is shown by point 2 on y-axis

In second interval 10 - 19 there are five numbers ( 10, 11,11, 14, 18 )so, this is shown by point 5 on y-axis.

In third interval 20 - 29 there are three numbers ( 28,28, 29 )so, this is shown by point 3 on y-axis.

In fourth interval 30 - 39 there is no data to plot so, this interval will be blank.

In fifth interval 40 - 49 there are six numbers ( 40,41, 41,44,45,47 )so, this is shown by point 6 on y-axis.

In sixth interval 50 - 59 there is one number ( 55 )so, this is shown by point 1 on y-axis.

All these interpretation matches the <u>second graph from the top left side.</u>

If the tax rate is 9.5%. determine how much tax you will need to pay on your order

7nadin3 [17]

Answer:

In order to calculate the sales tax of an item, we need to first multiply the pre-tax cost of the item by the sales tax percentage after it has been converted into a decimal. Once the sales tax has been calculated it needs to be added to the pre-tax value in order to find the total cost of the item.

6) subtract 16 on both sides

then it should be x/4>18

then you would times 18 by 4 and get

The following table gives results from two groups of students who took a nonproctored test. Use a 0.01 significance level to tes

Nana76 [90]

Answer:

Original claim is $\mu_{1} =\mu_{2}$

Opposite claim is $\mu_{1} \neq \mu_{2}$

Null and alternative hypotheses:

$H_{0}:\mu_{1} = \mu_{2}$

$H_{1} : \mu_{1} \neq \mu_{2}$

Significance level: 0.01

Test statistic:

We can use TI-84 calculator to find the test statistic and P-value. The steps are as follows:

Press STAT and the scroll right to TESTS

Scroll down to 2-SampTTest... and scroll to stats.

Enter below information.

$\bar{x_{1}}=70.29$

$Sx1=22.09$

$n_{1} = 30$

$\bar{x_{2}}=74.26$

$Sx2=18.15$

$n_{2} = 32$

$\mu_{1} \neq \mu_{2}$

Pooled: Yes

Calculate.

The output is in the attachment.

Therefore, the test statistic is:

$t=-0.78$

P-value: 0.4412

Reject or fail to reject: Fail to reject

Final Conclusion: Since the p-value is greater than the significance level, we, therefore, fail to reject the null hypothesis and conclude that the there is sufficient evidence to support the claim that the samples are from populations with the same mean.
