A random sample of 340 electronic components manufactured by a certain process are tested, and 30 are found to be defective. A device will be manufactured in which two of the components will be connected in series. The components function independently, and the device will function only if both components function. Let q be the probability that a device functions. Find a 95% confidence interval for q. Round the answers to three decimal places. The 95% confidence interval for q is (
Answer:
95% of the confidence interval for q is
(0.05809 , 0.1183)
Step-by-step explanation:
Step:1
Given that the random sample of 340 electronic components manufactured by a certain process is tested, and 30 are found to be defective.
sample proportion
[tex]q^{-} = \frac{x}{n} = \frac{30}{340} = 0.0882[/tex]
Step:2
95% of the confidence interval is determined by
[tex](q - Z_{0.05} \sqrt{\frac{pq}{n} } , q + Z_{0.05} \sqrt{\frac{pq}{n} } )[/tex]
[tex]((0.0804 -1.96 \sqrt{\frac{0.0804 X0.9118}{340} } ,0.0804 +1.96 \sqrt{\frac{0.0804 X0.9118}{340})[/tex]
[tex]( 0.0882- 1.96 \sqrt{0.000236} , 0.0882 + 1.96 \sqrt{0.000236} )[/tex]
(0.0882 - 0.03011 , 0.0882+0.03011)
( 0.05809 , 0.1183)
Final answer:-
95% of the confidence interval for q is
(0.05809 , 0.1183)

What is the equation of a circle with center (-5, 8) and radius 9?
Answer:
Your equation is:
(x−5)2+(y+8)2=92
Expanding from general form you can write this as:
x2−10x+y2+14y+−8=0
Step-by-step explanation:
i think its correct ig don't know sry but i tried hope it helps you ✨
Answer:
[tex](x+5)^2+(y-8)^2=81[/tex]
Step-by-step explanation:
General equation of a circle is [tex](x-a)^2+(y-b)^2=r^2[/tex].
Center coordinates = (-5, 8)
a = -5 b = 8 r = 9
[tex]\\(x+5)^2+(y-8)^2=9^2[/tex]
[tex](x+5)^2+(y-8)^2=81[/tex]

Use linear regression to find an equation that would best predict a fair home price based on the
comps given below. Round each variable to 4 decimal places.
Answer:
y = 0.0807x - 3.4286
Step-by-step explanation:
Given the data above :
X :
1400
1700
1500
Y:
108
133
120
Using a linear regression calculator, the regression equation obtained is :
y = 0.0807x - 3.4286
Slope = 0.0807
Intercept = - 3.4286
x = predictor variable
y = predicted variable

You are given the results of measurement of resistors. We are testing the
measurement tool. It will pass the technical control if the mean value will be
in the range [198-202] with standard deviation less than 3 Ohms. Will the tool
pass the technical control?
Answer:
As both the standard deviation and the mean have the desired values, the tool passes the technical control.
Step-by-step explanation:
Mean:
The mean is the sum of all values divided by the number of values.
[tex]M = \frac{199+204+201+197+195+204+200}{7} = 200[/tex]
The mean is in the desired range.
Standard deviation:
The standard deviation is the square root of the sum of the difference squared between each value and the mean, divided by the number of values.
[tex]S = \sqrt{\frac{(199-200)^2+(204-200)^2+(201-200)^2+(197-200)^2+(195-200)^2+(204-200)^2+(200-200)^2}{7}} = 1.18[/tex]
As both the standard deviation and the mean have the desired values, the tool passes the technical control.

What number is halfway between 0.36 and 0.48 on a number line?
Answer:
0.42
Step-by-step explanation:
they are both multiples of 0.06
think of it like 6 x 6= 36 and 6 x 8 = 48
6 x 7 = 42 would be halfway
Answer:
0.42
Step-by-step explanation:
To find the half, add da numbers and divide by 2. So 0.36 and 0.48 added together is 0.84. That divided by 2 is 0.42.

What is the rate of change of the function y
- 2 x – 52
Answer:
The rate of change is -2
Step-by-step explanation:
Given
[tex]y = -2x - 52[/tex]
Required
The rate of change
The slope intercept of a fuction is:
[tex]y =mx + b[/tex]
Where
[tex]m \to[/tex] rate of change
So, by comparison; [tex]y = -2x - 52[/tex] and [tex]y =mx + b[/tex]
[tex]m = -2[/tex]
