Social psychologist notes that the average time a person spends on social media is 2 hours a day. The researcher wants to test whether new parents spend more or less time than 2 hours on social media. She records the following numbers of hours spent on social media and a sample of 15 new parents: 0, 4, 1, 2, 2, 3, 0, 4, 3, 5, 2, 1, 1, 0, 2. (a) Test the hypothesis of whether new parents spend more or less than 2 hours a day on social media using a .05 level of significance. State the value of the test statistic and the decision to retain or reject the null hypothesis

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
