= <u>187.3 yards</u>
Step-by-step explanation:
The set-up will represent a triangle whereby the :
- Width = Height = 150 yards
- Diagonal = Hypotenuse = 240 yards
- Length = Base = ?
Answer:
The decision made by the researcher based on this information is to reject the null hypothesis.
Step-by-step explanation:
Two-tailed hypothesis test:
Critical value: 
Test statistic: z
If 
, we do not reject the null hypothesis.
If 
, we reject the null hypothesis.
In this question:
Since , we reject the null hypothesis.
The decision made by the researcher based on this information is to reject the null hypothesis.
Answer:
A
Step-by-step explanation:
you can just plug in the numbers until they come out equal
Answer:
Step-by-step explanation:
Given: Hector saved twice as much money as Sam.
Ted saved $100 more than Hector.
Gina saved $50 less than Ted.
As given, lets assume the amount of money Sam has in saving be "x".
Now, finding saving of each person given.
Writing the algebric expression of each´s saving amount.
we know, Hector saved twice as much money as Sam.
∴ Hector saving= 
Also, Ted saved $100 more than Hector.
∴ Ted´s saving= 
Next finding Gina´s saving
As given, Gina saved $50 less than Ted.
∴ Gina´s saving= 
Opening parenthesis and solving it.
⇒ Gina´s saving= 
Algebric expression of Gina´s saving=
Complete question:
Dr. Lyte wishes to study speed of Reaction Time to press a button in response to the onset of a lamp. The independent variable (V) is the color of the light produced by the lamp (red, orange, yellow, green, or blue) Since only 10 participants are available, she elects to administer the IV within-subjects with all 10 participants being exposed to all five levels of the color variable. The order of the color of the light presentation is to be counterbalanced. Using concepts from the textbook, why would Dr. Lyte need to use counterbalancing in this scenario?
Answer:
Here,
Independent variable (IV) is: the color of the light produced by the lamp (red, orange, yellow, green, or blue)
We are also told only 10 participants are available.
All 10 participants are being exposed to all five levels of the color variable in the same order.
Counterbalancing is said to be a technique used when establishing task order. It helps prevent introduction if cofounding variables.
Dr. Lyte will need to use counterbalancing technique in this scenario because some of the participants may be unable to understand difference in similar colours. Example some participants may not be able to differentiate between orange and red when the red colour comes after orange.
But using counterbalancing technique, Dr. Lyte can avoid such an error.
