There is a positive correlation between the number of times the Striped Ground Cricket chirps per second and the temperature in

degrees Fahrenheit. If a scatter plot is made with the number of chirps on the horizontal axis and the trend line is found to be y = 3x + 25, then what would you predict the temperature in degrees Fahrenheit to be when there are 20 chirps per second?

Answer:

85 °F


Step-by-step explanation:

The trend line equation is given by  y=3x+25

Where,

  • x is the number of chirps per second, and
  • y is the temperature in degrees Fahrenheit

We want to find the temperature when the number of chirps is 20. So we plug in 20 into x and figure out y :

y=3x+25\\y=3(20)+25\\y=60+25\\y=85

Peter wants to test an assumption on the number of trees that tested positive for a particular infestation. He decides to focus
LUCKY_DIMON [66]

Answer:

H0 : P ≤ 0.12

H1 : P > 0.12

Step-by-step explanation:

12% = 12/ 100 = 0.12

Given the population proportion, P = 0.12

The claim is the alternative hypothesis, H1 ; which is to test if more than 12% of trees have been infested.

Hence, the alternative hypothesis will be ;

H1 : P > 0.12

The null hypothesis which is the initial truth is always the opposite of the alternative hypothesis, Therefore, we write our null as ;

The null hypothesis ; H0 : P ≤ 0.12

Therefore, we have :

H0 : P ≤ 0.12

H1 : P > 0.12
