(08.01 MC)Below are the data collected from two random samples of 500 American students on the number of hours they spend in school per day (rounded to the nearest hour): Number of hours in school per day45678

Sample B: Number of students809012012585

Meg concludes that students spend a mean of 7 hours in school each day. Tara thinks the mean is 6 hours. Who is correct—Meg or Tara? Explain your answer in two or three sentences. Make sure to use facts to support your answer.

The mean time spent in school is approximately 6 hours each day and Tara is correct

Step-by-step explanation:

The given data is presented here as follows;

Number of hours in school per day,      4,        5,        6,        7,         8

Sample A:,                                               70       100    125      135       70

Sample B:,                                               80        90     120     125      85

For sample A, we have;

The total number of hours spent by sample A = 4 × 70 + 5 × 100 + 6 × 125 + 7 ×135 + 8 ×70 = 3035 hours

The number of students in sample A = 70 + 100 + 125 + 135 + 70 = 500

The mean number of hours spent in school by sample A = 3035 /500 = 6.07

For sample B, we have;

The total number of hours spent by sample A = 4 × 80 + 5 × 90 + 6 × 120 + 7 ×125 + 8 ×85 = 3045 hours

The number of students in sample A = 80 + 90 + 120 + 125 + 85 = 500

The mean number of hours spent in school by sample A = 3045 /500 = 6.09

The cumulative data, we have;

(3035 + 3045)/1000 = 6.08

Therefore, the mean is approximately 6 hours each day and Tara is correct.

step-by-step explanation:

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
