5 0

Answer:

AB = 78

Step-by-step explanation:

Using Pythagoras' identity in the righr triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AB² = 72² + 30² = 5184 + 900 = 6084 ( take the square root of both sides )

AB = \sqrt{6084} = 78

Consider this quote: "In a recent survey, 65 out of 100 consumers reported that they preferred plastic bags instead of paper bag
Evgen [1.6K]

Answer:

Step-by-step explanation:

The p value (probability of obtaining results as extreme the z score if null is true) is usually the value derived to make a conclusion and in this case the p value is 0.03

The level of significance is the value usually compared with the p value which is 0.05

The sample promotion is 65 out of 100 = 65/100 = 0.65

The sample size is the total number of consumers which is 100

The null value is usually the default value. The null value would assume that there is no difference in the proportions who prefer each type in the population. There are two preferences: 100/2 = 50- 0.5 for each preference.
