Each flow element requires a test gauge ---> 32*80 = $2560
Each flow element needs total of 6 feet of tubing ----> 32*6 = 192 ft
price per foot = 6/100 = $.06
-----> 192*.06 = $11.52
Each 3-ft length of tubing requires 2 connectors. ----> (192/3)*2 = 128
-----> 128*2.5 = $320
Total Cost = 2560 + 11.52 + 320 = $2891.52
Subtract from budget:
3000 - 2891.52 = $108.48
Answer:
False.
Step-by-step explanation:
The probability that a randomly selected client at Bernie's salon has black hair is 61 / 264.
<h3>What is the probability?</h3>
Probability measures the odds that a stated event would occur. The odds the event happens lies between 0 and 1.
The probability that a client at Bernie's salon has black hair = number of clients with black hair / total number of clients
122 / 528 = 61 / 264

Answer:
H0 : μd = 0
H1 : μd ≠ 0
Test statistic = 0.6687 ;
Pvalue = 0.7482 ;
Fail to reject H0.
Step-by-step explanation:
H0 : μd = 0
H1 : μd ≠ 0
Given the data:
Before: 15 26 66 115 62 64
After: 16 24 42 80 78 73
Difference = -1 2 24 35 -18 -9
Mean difference, d ; Σd / n
d = Σx / n = ((-1) + 2 + 24 + 35 + (-18) + (-9))
d = Σx / n = 33 / 6 = 5.5
Test statistic = (d / std / sqrt(n))
std = sample standard deviation = 20.146
Test statistic = 5.5 ÷ (20.146/sqrt(6))
Test statistic = 0.6687
The Pvalue :
P(Z < 0.6687) = 0.7482
At α = 0.05
Pvalue > α ; Hence we fail to reject H0
The data does not suggest a significant mean difference in the average number of accidents after information was added to road signs.
