In 1999, 2.2% of all cars in the United States were reported stolen. In a random sample of 400 Nissan Maxima cars 12 were reported stolen during 1999. If the percentage of thefts for Nissan Maxima cars is the same as the national percentage of 2.2%, what is the probability that the percentage of thefts ina random sample of 400 would be greater than or equal to 3%

The probability of  the percentage of thefts in a random sample of 400 would be greater than or equal to 3 is  given by  P (z> 1.09)   = 0.1379

Step-by-step explanation:

The statistic

z= p^- p / √pq/n

is used to measure the difference between the sample and population proportions.

Here p^= 12/400= 0.03

p= 0.022               q= 1-0.022=0.978

 and n=400

Putting the values

Z= 0.03-0.022/√0.022(1-0.022)/400

Z= 0.008/√0.022(0.978)/400

Z= 0.008/0.00733

z= 1.090

We have to find the probability of  the percentage of thefts in a random sample of 400 would be greater than or equal to 3

or

Mathematically

P (z> 1.09)= 1- P (z≤1.09)

                  = 1- 0.8621   ( from the z area table)

                   = 0.1379

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

the answer is d
