Do teenage boys and teenage girls have significantly different social media habits? A sociologist wants to examine this question at the a = 0.01 level of significance. Let H3 represent the average time spent by a teenage boy on social media per day and Hc represent the average time spent per day on social media by a teenage girl. (Round your results to three decimal places) Which would be correct hypotheses for this test? O Ho : HB - HG = 0, H1: HB - HG + 0 O Ho: HB - HG = 0, H1: HB - HG > 0 Ho:HB - HG 0, H1: µB - HG = 0 Ho : HB - HG = 0, H1:HB - PG <0 A random sample of 42 teenage boys spent an average of 95.6 minutes on social media, with a standard deviation of 3. A random sample of 44 teenage girls spent an average of 97.8 minutes on social media, with a standard deviation of 2.7. Find the test statistic (2 decimals): Give the P-value (4 decimals): Which is the correct result: O Do not Reject the Null Hypothesis O Reject the Null Hypothesis Which would be the appropriate conclusion? O There is not significant evidence to suggest that boys and girls differ in their social media habits. O There is significant evidence to suggest that boys and girls differ in their social media habits.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
