Using traditional methods, it takes 9.5 hours to receive a basic flying license. A new license training method using Computer Ai
Aleonysh [2.5K]

Answer:

Step-by-step explanation:

Null hypothesis: u = 9.5hrs

Alternative: u =/ 9.5hrs

Using the t test

t = x-u/sd/√n

Where x is 10hrs, u is 9.5, sd is 1.6 and n is 15

t = 10-9.5 / (1.6/√15)

t = 0.5 / (0.4131)

t = 1.21

In order to make a conclusion, we have to find the p value at a significance level lot 0.1. The p value is 0.2263 which is greater than 0.1. This, we will fail to reject the null hypothesis and conclude that there is not enough statistical evidence to prove that the technique performs differently than the traditional method.

You and your friend decide to get your cars inspected. You are informed that 71​% of cars pass inspection. If the event of your​
Ostrovityanka [42]

Answer:

a) 0.71

b) 0.29

c) 0.50

d) 0.91

Step-by-step explanation:

To get the probability that your car pass inspection we use the given information,  if we are informed that 71​% of cars pass inspection, that means that from 100 cars ,  71 pass the inspection.  

P=# of possibilities that meet the condition / #of equally likely possibilities.

a) So, the  probability that your car passes​ inspection is

P(passing) =71/100=0.71

b) We have two options,  passing or not passing the inspection and the Complement Rule states that the sum of the probabilities of an event and its complement must equal 1.

So,  the probability of not passing is

P(not passing)= 1- P(passing)

P(not passing)= 1- 0.71=0.29

c) When we need to know the probability of 2 event happening at the same time,  we multiply both probabilities.

The probability that both of the cars​ pass= the probability of passing our car*  the probability of passing the car of your friend

P(both passing) =0.71*0.71=0.50

d) The probability that at least one of the two cars​ passes is

P=1 - (P(not passing))^2=0.91

Marina CMI [18]
To find the area that is the closest, use the formula for finding the area of a circle.

A = pi x r^2
      3.14 x 25^2
A = 1962.5 square feet

This is closest to answer choice D.

Vlada [557]

Answer:

C + 1 < 3 is not equivalent.

Step-by-step explanation:

B - 1 < 2 ⇒ B < 3

C + 1 < 3 ⇒ C < 2

D - 2 < 1 ⇒ D < 3

Therefore, all inequalities are equivalent except C + 1 < 3.
