Step-by-step explanation:

Answer:

b. There is sufficient evidence to indicate that exactly 65% of all e-commerce shoppers fail in their attempts to purchase merchandise on-line because Web sites are too complex.

Step-by-step explanation:

Not significant,accept null hypothesis that population proportion = 0.65

When we accept the null hypothesis that P= 0.65

Then only option b is correct which states that  there is sufficient evidence to support that population proportion is exactly 0.65 .

1) We obtain a P - value of 0.0522 which is greater than 0.5 indicating that the null hypothesis is not rejected.

The rejection region for this right-tailed test is z > 1.64

2) Test Statistics

z= p`-p0/ sqrt(p0(1-p0)/n)

The z-statistic is computed as follows:

z= 0.75-0.65/ √(0.65*0.35)60

z= 1.624

3) Decision about the null hypothesis

Since it is observed that z = 1.624 is less than z ∝=1.64, it is then the null hypothesis is not rejected.

Answer:

A

Step-by-step explanation:

The other piece of information Mike needs to determine the confidence interval is the critical value.

A confidence interval is a range of estimates for a variable that is uncertain. A confidence interval is calculated at a specified confidence level; the 95% confidence level is the most frequent, although other values, such as 90%or 99%, are also used.

To determine the confidence interval for a set of data sample size, the sample proportion, and the critical value are needed to be known.

Hence, the other piece of information Mike needs to determine the confidence interval is the critical value.

Answer:

[tex] m = \sqrt{125} [/tex]

Step-by-step explanation:

By geometric mean property:

[tex] {n}^{2} = 5 \times 20 \\ {n}^{2} = 100 \\ \\ By \: Pythagoras \: Theorem \\ {m}^{2} = {n}^{2} + {5}^{2} \\ {m}^{2} = 100 + 25 \\ {m}^{2} = 125 \\ m = \sqrt{125} [/tex]

Given:

The expression is

[tex](2x^2+4x-7)(x-2)[/tex]

To find:

The expression which is not a correct way to rewrite the given expression.

Solution:

We have,

[tex](2x^2+4x-7)(x-2)[/tex]

Using distributive property, we get

[tex]=(2x^2)(x-2)+(4x)(x-2)+(-7)(x-2)[/tex]

[tex]=(2x^2)(x)+(2x^2)(-2)+(4x)(x)+(4x)(-2)+(-7)(x)+(-7)(-2)[/tex]

Using distributive property the given expression can rewritten as:

[tex]=(2x^2+4x-7)(x)+(2x^2+4x-7)(-2)[/tex]

Only the expression in option A is not a correct way to rewrite the given expression because [tex](2x^2+4x-7)[/tex] is not distributed to [tex](x-2)[/tex] properly.

Therefore, the correct option is A.

Answer:

Answer:

The answer is "Type 1 error".

Step-by-step explanation:

The error of type I, frequently known as a 'false positive': its error in judgment that perhaps a null hypothesis is simply rejected. This is the mistake of accepting a possible (actual interest hypothesis) hypothesis whenever the results could be attributed to chance since the researchers deny, if valid, the null hypothesis.

Step-by-step explanation:

Answer:

mean = 49.25

Step-by-step explanation:

mean = sum of all the number ÷ amount of number

mean = 56 + 21 +55 + 30 + 34+ 76 + 40 + 82 = 394 ÷ 8

mean = 49.25

mean absolute deviation = (56- 49.25) + (21 - 49.25) + (55 -49.25) + (30 - 49.25) + (34 -49.25) + (76 -49.25) + (40 - 49.25) + (82- 49.25) / 8

mad= 6.75 + -28.25 + 5.75 + -19.25 + -15.25 + 26.75 + -9.25 + 32.75 / 8

mad = 0/8

mad= 0

Answer:

Experimental probability is the result of an experiment. Theoretical probability is what is expected to happen. Three students tossed a coin 50 times individually.

Step-by-step explanation:

Experimental probability is found through experiments while theoretical probability are not.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

Theoretical probability is the probability that we use normally which describes the percent or probability that an event is likely to happen. This is found using logic.

Experimental probability is the probability that we calculate through the actual experiments that describes the frequency of an event happening. This is found using experiments which are repeated.

They can be same, both of which describes the probability of happening an event.

Hence the experimental probability is found through experiments while theoretical probability are not.

Answer:

  a) radius: 6 (m); mass: 22 (kg)

  b) volume: 19 (m³)

  c) d ≈ 2.8×10^3 kg/m³

Step-by-step explanation:

The order of magnitude is the exponent of 10 when the number is written in scientific notation.

a) radius: 1.6×10^6 m, so the order of magnitude is 6 when the units are meters.

  mass: 4.8×10^22 kg, so the order of magnitude is 22 when the units are kg.

__

b) The volume is ...

  V = (4/3)πr^3 ≈ 1.716×10^19 m^3, so the order of magnitude of the volume is 19 when the units are m^3.

__

c) The ratio of mass to volume is ...

  d = (4.8×10^22)/(1.716×10^19) ≈ 2.8×10^(22-19) = 2.8×10^3 kg/m^3, so the order of magnitude is 3 when the units are kg/m^3.

Answer:

$97.17

Step-by-step explanation:

First, subtract 85 from 668:

668 - 85

= 583

This means that our budget for all of the days excluding the last day is $583

To find how much can be spent on the remaining days, divide 583 by 6:

583/6

= 97.17

So, approximately $97.17 can be spent on the remaining days
