Answer:
The p value for this case would be given by"
For this case since the p value is higher than the significance level we don't have enough evidence to conclude that the true mean is significantly different from 6.5 lbs/square inch at 10% of significance. So then there is not enough evidence to conclude that the valve does not perform to the specifications
Step-by-step explanation:
Information given
represent the sample mean
represent the population deviation
sample size
represent the value that we want to test
represent the significance level
z would represent the statistic
represent the p value for the test
Hypothesis to verify
We want to verify if the true mean for this case is equal to 6.5 lbs/square inch or not , the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is given by:
(1)
And replacing we got:
The p value for this case would be given by"

Answer: $608.24
Step-by-step explanation:
Hi, first we have to calculate the percentage amount of the discount.
We have to multiply the cost by the sale percentage in decimal form.
703 x (16/100) =703 x 0.16 =112.48
Then, we have to subtract that amount to the original cost.
703-112.48 = 590.52
Then, we have to calculate the sale tax amount by multiplying the sale cost by the tax percentage in decimal form.
590.52 x (3/100) = 590.52 x 0.03 =17.7156
Finally adding that amount to the sale cost.
590.52 +17.7156 = $608.24
The answer for A . 2/3
The answer for B. 1 1/4
Explain
4 pound of flout / 6 loaves
4/6
The common for both number is 2
Divide by 2
4/2 = 2
6/2 = 3
And for b
Here the picture
Below

Hence the value of a is: 3b/2
if I'm correct, 3 would be 78 as well . I'm so sorry if I get this wrong . I struggled a bit with this part and math a lot , and I only worked on it for like 2 days and then I had to test for it
