Answer:
= ( -4.725, 6.945) pg/ml
Therefore at 95% confidence interval (a,b) = ( -4.725, 6.945) pg/ml
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean gain x = 1.11 pg/ml
Standard deviation r = 15.18 pg/ml
Number of samples n = 26
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
1.11+/-1.96(15.18/√26)
1.11+/-1.96(2.977042931397)
1.11+/-5.835004145539
1.11+/-5.835
= ( -4.725, 6.945) pg/ml
Therefore at 95% confidence interval (a,b) = ( -4.725, 6.945) pg/ml
Answer:
x = 100°
y = 125°
z = 55°
Step-by-step explanation:
A straight line is 180°
A triangle is 180°
Solve in this order:
X: 180 - 80 = 100
Z: 180 - 80 - 45 = 55
Y: 180 - 55 = 125
The <em>approximate</em> price for an ornamental bookcase from Germany and with a cost of EUR 830 on November 26, 2019 is equal to 753.64 USD.
<h3>How to determine the price of a good in terms of a foreign currency</h3>
Herein we have an application of <em>direct proportionality</em> model, now described:
y = k · x (1)
Where:
- x - Cost of the bookcase in Germany, in euros.
- k - Currency exchange rate, in US dollars per euros.
- y - Cost of the bookcase in the United States, in US dollars.
If we know that x = 830 EUR and k = 0.908 USD/EUR, then the cost of the bookcase in the United States is:
y = (830 EUR) · (0.908 USD/EUR)
y = 753.64 USD
The <em>approximate</em> price for an ornamental bookcase from Germany and with a cost of EUR 830 on November 26, 2019 is equal to 753.64 USD.
