Answer:

885

Step-by-step explanation:

Given:  Amount available in the cash register= $ 125.50.

            Every item is just priced at $1.00

            Total amount of money at the end of day= $1085.60

            Sales tax rate= 8.5%

First finding total revenue generated at the end of day,

Total revenue at the end of day= Total\ cash\ at\ the\ end\ of\ day - Cash\ available\ at\ the\ beginning\ of\ day

∴ Total revenue at the end of day= 1085.6- 125.5= \$ 960.1

Lets assume total number of item sold be "x".

Now, forming an equation to determine the total revenue generated at the end of day.

We know, Total revenue is the number of item sold at $1 and sales tax revenue generated on the number of item sold.

⇒ \$1 \times x + \frac{8.5}{100} \times x= \$ 960.1

⇒1x+0.085x= 960.1

⇒ 1.085x= 960.1

dividing both side by 1.085

⇒x= \frac{960.1}{1.085}

∴ x= 884.884 \approx 885

Hence, total number item sold in the day is 885

Park officials make predictions of times to the next eruption of a particular​ geyser, and collect data for the errors​ (minutes
nalin [4]

Answer:

a) Null hypothesis: \mu =0

Alternative hypothesis: \mu \neq 0

b) t =-7.44

c) p_v = 2*P(t_{98}

d) Reject Null hypothesis. The is enough evidence to conclude that the mean prediction error is not equal to 0.

We reject the null hypothesis because the p_v. So we can conclude that the difference is significantly different from 0 at 5% of significance.

Step-by-step explanation:

Assuming this output:

t_{difference}=-0.395

t(observed value) =-7.44

t(Critical value )= 1.984

DF = 98

p value (two tailed) < 0.0001

\alpha =0.05

a) What are the null and alternative hypothesis

Null hypothesis: \mu =0

Alternative hypothesis: \mu \neq 0

The reason is because the output says a bilateral test so for this case w eselect this option.

b) Identify the statistic

The correct formula for the statistic is given by:

t=\frac{\bar X_1 -\bar X_2 -0}{\sqrt{(\frac{s^2_1}{n_1}+\frac{s^2_2}{n_2})}}

Based on the output the calculated value its t =-7.44

c) Identify the p value

We have the degrees of freedom given 98

Based on the alternative hypothesis the p value is given by:

p_v = 2*P(t_{98}

d) State the final conclusion that addresses the original claim

Reject Null hypothesis. The is enough evidence to conclude that the mean prediction error is not equal to 0.

We reject the null hypothesis because the p_v. So we can conclude that the difference is significantly different from 0 at 5% of significance.
