On calculator it means -

4.6 x $10^{-7}$ .

We have 4.6 E −7.

We have to determine what it represents on calculator.

<h3>What is Scientific Notation ?</h3>

Scientific notation is a way of writing very large or very small numbers in the powers of 10.

According to the question, we have -

4.6 E−7

On calculator it means -

4.6 x $10^{-7}$

This is in the form of Scientific Notation.

Obtain or compute the following quantities.

Answer:

a) $F_{0.05,4,7}=0.16$

b) $F_{0.05,7,4}=0.24$

c) $F_{0.95,4,7}=4.12$

d) $F_{0.95,7,4}=6.09$

e) $F_{0.99,8,12}=4.50$

f) $F_{0.01,8,12}=0.18$

g) $P(F_{5,4} \leq 6.26)=0.95$

h) $P(0.177 \leq F_{10,5} \leq 4.74)=0.94$

Step-by-step explanation:

(a) F0.05, 4, 7 (Round your answer to two decimal places.)

For this case we need a valueof the F distribution with 4 degrees of freedom for the numerator and 7 for the denominator that accumulates 0.05 of the area on the left tail. We can use the following excel code: "=F.INV(0.05,4,7)". And we got:

$F_{0.05,4,7}=0.16$

(b) F0.05, 7, 4 (Round your answer to two decimal places.)

For this case we need a valueof the F distribution with 7 degrees of freedom for the numerator and 4 for the denominator that accumulates 0.05 of the area on the left tail. We can use the following excel code: "=F.INV(0.05,7,4)". And we got:

$F_{0.05,7,4}=0.24$

(c) F0.95, 4, 7 (Round your answer to three decimal places.)

For this case we need a valueof the F distribution with 4 degrees of freedom for the numerator and 7 for the denominator that accumulates 0.95 of the area on the left tail. We can use the following excel code: "=F.INV(0.95,4,7)". And we got:

$F_{0.95,4,7}=4.12$

(d) F0.95, 7, 4 (Round your answer to three decimal places.)

For this case we need a valueof the F distribution with 7 degrees of freedom for the numerator and 4 for the denominator that accumulates 0.95 of the area on the left tail. We can use the following excel code: "=F.INV(0.95,7,4)". And we got:

$F_{0.95,7,4}=6.09$

(e) the 99th percentile of the F distribution with v1 = 8, v2 = 12 (Round your answer to two decimal places.)

So for this case we need a value on the F distribution with 8 degrees of freedom for the numerator and 12 for the denominator that accumulates 0.99 of the area on the left tail. And we can use the following excel code: "=F.INV(0.99,8,12)". And we got:

$F_{0.99,8,12}=4.50$

(f) the 1st percentile of the F distribution with v1 = 8, v2 = 12 (Round your answer to three decimal places.)

So for this case we need a value on the F distribution with 8 degrees of freedom for the numerator and 12 for the denominator that accumulates 0.01 of the area on the left tail. And we can use the following excel code: "=F.INV(0.01,8,12)". And we got:

$F_{0.01,8,12}=0.18$

(g) P(F ≤ 6.26) for v1 = 5, v2 = 4 (Round your answer to two decimal places.)

For this case we want to find the probability that the F distribution with 5 degrees on the numerator and 4 on the denominator would be less or equal than 6.26. We can use the following excel code: "=F.DIST(6.26,5,4,TRUE)". And we got

$P(F_{5,4} \leq 6.26)=0.95$

(h) P(0.177 ≤ F ≤ 4.74) for v1 = 10, v2 = 5 (Round your answer to two decimal places.)

For this case we want to find the probability that the F distribution with 10 degrees on the numerator and 5 on the denominator would be between 0.177 and 4.74. We can use the following excel code: "=F.DIST(4.74,10,5,TRUE)-F.DIST(0.177,10,5,TRUE)". And we got

$P(0.177 \leq F_{10,5} \leq 4.74)=0.94$

The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed

Aleks [24]

Answer:

We are given:

$H_{0}: \mu = 33$

$H_{1}: \mu < 33$

Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed.

Since the alternative hypothesis has less than sign, therefore the given hypothesis is left-tailed

What parameter is being tested?

The parameter used is $\mu$ , which denotes the population mean.

Please note:

The type is test determined based on the alternative hypothesis.

If the alternative hypothesis has $\neq$ sign, it means the hypothesis test is two-tailed

If the alternative hypothesis has $>$ sign, it means the hypothesis test is right-tailed

If the alternative hypothesis has sign, it means the hypothesis test is left-tailed

Pygmies do not plant their own , but they will work in them in exchange for food or tools

Lady_Fox [76]

I’m not sure where the question is here, but if it is a true or false, the pygmies do exchange with neighboring villages. They are hunters and gatherers, so rather than planting food, they gather. So this statement would be true

Jameson is seeking a loan with a simple interest rate of 3% per year. If he wants to borrow $8000, then how much will he be char

Gnom [1K]

Answer:

The value of interest charged after 4 years = $ 960

Step-by-step explanation:

Principal amount P = $ 8000

Rate of interest R = 3 %

Time = 4 year

Simple interest = $\frac{P R T}{100}$
