Breyers is a major producer of ice cream and would like to test the hypothesis that the average American consumes more than 17 o
zhenek [66]

Answer:

The p-value would be 0.0939

Step-by-step explanation:

We can set a standard t-test for the Null Hypothesis that H_0: 18.2\geq 17

The test statistic then takes the form

t=\frac{18.2-17}{3.9/\sqrt{15}}=1.317

with this value we then can calculate the probability that is left to the right of this value P(X>1.317). From theory we know that t follows a standard normal distribution. Then P(X>1.317)=0.0939 which is smaller than the p-value set by Breyers of 0.10

Square root of 2 divided by the cube root of 2
kifflom [539]

Answer: \sqrt[6]{2}

Step-by-step explanation:

You know that the expression is \frac{\sqrt{2}}{\sqrt[3]{2}}

By definition we know that:

\sqrt[n]{a}=a^{\frac{1}{n}

You also need to remember the Quotient of powers property:

\frac{a^n}{a^m}=a^{(n-m)}

Therefore, you can rewrite the expression:

=\frac{2^{\frac{1}{2}}}{2^{\frac{1}{3}}}

Finally, you have to simplify the expression. Therefore, you get:

=2^{(\frac{1}{2}-\frac{1}{3})}\\=2^{\frac{1}{6}}\\=\sqrt[6]{2}
