The speeds of vehicles traveling on a highway are normally distributed with an unknown population mean and standard deviation. If a random sample of 38 vehicles is taken to estimate the mean vehicle speed, what t-score should be used to find a 99% confidence interval estimate for the population mean

The t-score of 2.715 should be used

Step-by-step explanation:

Degrees of freedom ==> n - 1 ==> 38 - 1 ==> 37

to find 99% confidence interval,  Hence,

Find t0.005 in front of 37 degrees of freedom,

Therefore the answer is, t-score = 2.715

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.
