Answer

test statistic $t = -2.27$

P-value $p- value = 0.0198$

Step-by-step explanation:

From the question we are told that

The first sample size is $n_1 = 5$

The first sample mean is $\= x_1 = 1.76 \ mm$

The first standard is $s_1 = 0.55$

The second is $sample \ size\ is\ n_2 = 11$

The second sample mean is $\= x_2 = 2.56$

The second standard deviation is $\sigma = 0.84$

The level of significance is $\alpha = 0.01$

The null hypothesis is $H_o : \mu_1 - \mu_2 = 0$

The alternative hypothesis is $H_a: \mu_1 - \mu_2 < 0$

Generally the test statistics is mathematically represented as

$t = \frac{ (\= x _1 - \= x_2) - ( \mu_1 - \mu_2)}{ \sqrt{\frac{s_1 ^2 }{ n_1 } + \frac{s_1 ^2 }{ n_1 } } }$

=> $t = \frac{ (1.76 - 2.56 ) - 0 }{ \sqrt{\frac{0.55^2 }{ 5 } + \frac{0.84^2 }{11 } } }$

=> $t = -2.27$

Generally degree of freedom is mathematically represented as

$df = n_1 + n_2 - 2$

=> $df = 5 + 11 - 2$

=> $df = 14$

From the student t distribution table the probability value to the left that corresponds to $t = -2.27$ at a degree of freedom of $df = 14$ is

$p- value = 0.0198$

dexar [7]

Answer:

791.2 ft

Step-by-step explanation:

The cable is inclined and this acts as the hypotenuse. Since the other two sides are given.

$H=\sqrt {x^{2}+y^{2}}$

where x and y represent the distance between two cliffs apart and difference in heights. Substituting 740 for x and 280 for y then

$H=\sqrt {740^{2}+280^{2}}=791.20161779409930627669981858168023442712 ft\approx 791.2 ft$

What is the correct answer to this multiple choice question? Please help!

erik [133]

Answer:

$\sqrt[3]{4}$

Step-by-step explanation:

To solve this we need to take the square root of both sides with a certain degree.

$4^6 = a^{18}$

We can take the root of both sides with a degree of 18.

$\sqrt[18]{4^6} = \sqrt[18]{a^{18}} \\(4^6)^{\frac{1}{18} } = a\\a = 4^{\frac{6}{18} } = 4^{\frac{1}{3} } = \sqrt[3]{4}$

It's helpful to understand that when a number has its square root taken with some degree n. The square root can be represented as just the value raised to the (1/n) power.

It's also helpful to understand that when you raise something to the power of another power, you can simply multiply the powers together. For instance (2^3)^5 = 2^15
