The effect of drugs and alcohol on the nervous system has been the subject of considerable research recently. Suppose a research

neurologist is testing the effect of a drug on response time by injecting 150 rats with a unit of dose of the drug, subjecting each to neurological stimulus, and recording its response time. The neurologist knows that the mean response time for rats not injected with the drug (the "control" mean) is 1.2 seconds. S/he wishes to test whether the mean response time for the drug-injected rats is greater than 1.2 seconds. If the sampling experiment is conducted with the sample mean equal to 1.05 second, set up the test of hypothesis for this experiment and determine if the results are significant. Suppose drug-injected rats have a mean response time of 1.1 .seconds, that is mu = 1.1 seconds.
Calculate the value of beta corresponding to the two rejection regions.

Answer:

Julia found 5 coins

Step-by-step explanation:

lets take the # of coins julia found as "x"

alice found6

davi found 5

lucas found 6

and carter found 8

remember how to calculate mean( add all numbers and divide by the# of numbers)

so

6+5+6+8+x/5=6 (since there are "5" terms)

so

25+x/5=6

treat this like a linear equation so multiply by 5 on both sides

25+x/5(5)=6(5)

25+x=30

subtract "25 on both sides"

25-25+x=30-25

x=5

hope this helps

Today only, a sofa is being sold at a 72% discount. The sale price is 218.40.
EastWind [94]

Answer:

780

Step-by-step explanation:

Let x be the original price

x - x*72% is the new price

x - .72x = 218.40

.28x = 218.40

Divide each side by .28

.28x/.28 = 218.40/.28

x =780

The sales tax rate in New Mexico is $5.125%.
madreJ [45]

Answer:

<em>The tax is $1.54 and the price after tax is $31.54</em>

Step-by-step explanation:

<u>Percentages</u>

The procedure to add a percentage ratio p to a given quantity q is:

* Calculate the increase as i = p*q/100

* Add the increase to the original quantity to get the final quantity f=q + i

It's given the sales tax rate in New Mexico is p=5.125%. A pair of pants in New Mexico costs q=$30 before tax.

* The increase (tax) is i = (5.125*30)/100 = $1.54

* The price after tax is f = $30 + $1.54 = $31.54

The tax is $1.54 and the price after tax is $31.54
