A study was done by a social media company to determine the rate at which users used its website. A graph of the data that was collected is shown: A line graph with Number of Months on the x axis and Number of Users, in thousands, on the y axis. The x axis has a scale from 0 to 27 in increments of 3. The y axis has a scale of 0 to 22 in increments of 2. A straight line connecting 0, 20 and 24, 15.5 is drawn. What can be interpreted from the range of this graph? The range represents the 24-month time period of the study. The range represents the number of users each month for 24 months. The range represents the 20-month time period of the study. The range represents the number of users each month for 20 months.

Anull hypothesis states that the difference between 8 hours of sleep and 3 hours of sleep has no effect on the number of pictures a student will remember during a picture memory interface test (pmit). examining the mit database, an extremely small t-value of 0.1611 is found. this t-value is much smaller than the smallest t-value on the chart for p-value reference. from this information we can: select one: a. accept the null hypothesis because the p-value obtained shows that the difference between the two groups being tested is not statistically significant b. accept the null hypothesis because the p-value obtained was statistically significant c. reject the null hypothesis because of the p-value obtained d. reject the null hypothesis because the data obtained is statistically significant
