A study was created to test the effects of jazz on people’s sleep patterns. The hypothesis of the experiment, 2 groups of people were created. Group I was placed in a quiet room where they went to sleep and they were timed on how long they slept. The group 2 was placed in a room where jazz music played softly as they began to sleep and played throughout the night. As each group awoke, their sleep times were monitored. What is the independent Variable ? And what is the Dependent Variable?

independent variable- Presence or absence of soft jazz music

Dependent variable - sleep time

Step-by-step explanation:

The independent variable refers to that variable that is manipulated in an experiment. The independent variable is being studied and its effect on the dependent variable is documented. Presence or absence of soft jazz music is the independent variable.

The dependent variable is the response variable. It is that factor that changes when the independent variable is manipulated. In this case, the sleep time of the participants in the study is the dependent variable.

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
