Population parameters are difficult to calculate due to

Mathematics
1 answer:
lilavasa [31]3 years ago
5 0

Answer:

1

option d

2

option a

Step-by-step explanation:

1)

The population is difficult to cover because it involves a lot of cost on procedure. Further, whole population is difficult to cover and it is infeasible to collect data on entire population. For example we want to check the quality of rice in production unit, we could n't test all grains of rice to check the quality rather than we take a portion of rice grains for quality check. Here, if the whole lot of a rice grains are taken then first drawback would be that it will be costly and second it is infeasible to collect data for whole lot of a rice grains.

2)

Teacher's union is planning to calculate the average salary for only high school teachers in a country and salaries for other teachers are not considered. So, from teachers population a sample of high school teacher in a country is selected. Thus, the calculated average will be sample statistic.

Graph the following function on the axes provided.
vitfil [10]

Step-by-step explanation:

step 1. graph f(x) = 2x + 6

step 2. y = mx + b. (slope intercept form)

step 3. b = 6 which is the y intercept so put a dot on (0, 6) or on the y axis at 6

step 4. m = 2 so put another dot up 2 and over to the right 1 from the y intercept

step 5. draw a line through your 2 points and you are done.

Answer:

sqrt(x+7) - log(x+2)

Step-by-step explanation:

f(x) = sqrt(x+7)

g(x) log(x+2)

f(x) - g(x) = sqrt(x+7) - log(x+2)

Which binomial is a factor of x4 − 4x2 − 4x 8?
Anastasy [175]

The given polynomial is

x^4-4x^2-4x-8

As this is a fourth degree polynomial, we can not directly use any formula, So here we will use hit and trial method

check whether x=-1 is a zero of the polynomial or not

(-1)^4-4(-1)^2-4(-1)-8=-7

Hence x=-1 is not a zero.

Now check whether x=-2 is a zero of the polynomial or not

(-2)^4-4(-2)^2-4(-2)-8=0

Hence x=-2 is a zero of the polynomial.

Hence we can re-write the polynomial as

x^4-4x^2-4x-8=x^4+2x^3-2x^3-4x^2-4x-8\\ \\ =x^3(x+2)-2x^2(x+2)-4(x+2)\\ \\ =(x+2)(x^3-2x^2-4)\\

Hence the required binomial is (x+2)

5.write a null hypothesis for the following: sunflower seeds planted in a wet soil will grow faster than sunflower seeds planted
Fynjy0 [20]

Null hypothesis is stated as H0: Sunflower seeds planted in well-drained soil will grow faster than sunflower seeds planted in wet soil.

Null hypothesis is defined as the hypothesis that stated that there is no relationship between the two population parameters. It is denoted by H0

To form the null hypothesis we take it as

   Null hypothesis : The sample data provides no evidence to support some claim being made by an individual.

Thus according to the question the null hypothesis can be stated as

 Null hypothesis, h0 : Sunflower seeds planted in well-drained soil will grow faster than sunflower seeds planted in wet soil.
