Answer:

y>\frac{7}{3}

Step-by-step explanation:

Solving an inequality is a lot like solving an equation, one uses inverse operations. The major difference between solving an inequality and an equation is that when one multiplies or divides by a negative number, then one must remember to flip the inequality sign, such a rule doesn't come into play in this case.

3y - 2 > 5

Inverse operations,

3y - 2 > 5

     +2    +2

3y > 7

/3   /3

y>\frac{7}{3}

yulyashka [42]

Answer:

4.10

0.17

Step-by-step explanation:

From the question, we know that

A recent sociological report stated that university students drink 4.10 alcoholic drinks per week on average, with a standard deviation of 1.9101.

Also, we're tasked with finding the mean and standard deviation of the sampling distribution of the sample mean alcohol consumption.

To find the mean of the sampling distribution, we take the sample mean of the same of that university students as a direct substitute. This then means that the mean of the sampling distribution of the sample mean alcohol consumption is 4.10 alcoholic drinks per week on average.

On the other hand, the standard deviation of the sampling distribution of the sample mean alcohol consumption is taken to be the division of the standard deviation of the sample mean. Mathematically, we have

Standard Deviation, S = 1.9101 / √125

Standard Deviation, S = 1.9101 / 11.18

Standard Deviation, S = 0.17

Therefore, the Standard Deviation is 0.17
