In a random sample of 500 handwritten zip code digits, 464 were read correctly by an optical character recognition (OCR) system
In-s [12.5K]

Answer:

z= 2.38

P = 0.008656

Step-by-step explanation:

Here n= 500 and p~= 464/500= 0.928 and q`= 1- 0.928 = 0.072

We formulate our null and alternate hypothesis as

H0 =  0.9 ;       H0 > 0.9

The degree of confidence = 90%

z₀.₀₅ = 1.645 for  α= 0.05

We use the test statistic

z=  x- np/√npq

z= 466-500 *0.9/ √500 * 0.9(1-0.9)

z= 466- 450/ √45

z= 16/6.7082

z= 2.38

As the calculated value of z= 2.38  is greater than α =1.645 so we reject H0.

If H0 is true the P value is calculated as

P = 1- Ф( 2.38)

P = 1-0.991344=0.008656

What is the formula to find the formula for a Pythagorean Theorem. What is length c if a is 3 inches and b is 4 inches?
REY [17]

Answer:

The formula of a Pythagorean Theorem is a^2 + b^2 = c^2

The length of c is 5 inches.

Step-by-step explanation:

a^2+b^2=c^2

3^2+4^2=c^2

25=c^2

Square root of 25= square root of c^2

5=c

Note that "^" means the number to the specified number.

Ex:      2^3

2 to the third power

or

2 cubed

Hope this helps!!!

Please consider this as brainliest thanks!!!

Can yu plz answer this inequality 3&lt;1/2x+1
Aleks04 [339]
First you need to change the equation to 3 < x/2 + 1

then we can treat it like a normal equation.

subtract 1 from each side to get 2 < x/2

then multiply both sides by 2 to get rid of the fraction and we have

4 < x and we switch it around to get 

x > 4 as our answer! :)
