Answer:

The countries with the lowest HDI scores are all located in Africa.

Explanation:

HDI and GDP have a negative relationship in the long term while the poverty rate and GDP have a positive relationship with the GDP. Meanwhile, in the short term, HDI and GDP have no relationship but the poverty rate and GDP have a relationship with GDP but it is a negative relationship.

The least developed country in the world with the lowest HDI in Niger, with an HDI of. 354. Niger has widespread malnutrition and 44.1% of people live below to the poverty line.

Answer:The countries with lower GDP are the same as those with the lowest HDI.

U GDP is a solid indicator of what a country's HDI will be.

Step-by-step explanation:

Which statements about countries with lower GDP and lowest HDI scores are accurate?

The countries with lower GDP are the same as those with the lowest HDI - human development index a measure of life expectancy, education and per capita income indicators.

The GDP rank tends to be associated with the lowest HDI.

U GDP - gross domestic product the total monetary value of goods and services in country at a specific time period is a solid indicator of what a country's HDI will be.

The GDP can be used to rank a country's HDI

Answer:

Step-by-step explanation:

The objective is to compute that more runs are scored in games for which DH is used

Let $\mu_1$ denote the population mean number of runs scored for DH group

Let $\mu_2$ denote the population mean number of runs scored for DH group

Let $n_1$ and $n_2$ denote the sample sizes for DH and no DH

From the available information

$n_1=n_2=20$

The population standard deviation of runs score is 2.54 for both the groups.

That is $\sigma _1^2=\sigma_2^2=2.54$

The null hypothesis is $H_0:\mu_1\leq \mu_2$

The alternative hypothesis is $H_1:\mu_1>\mu_2$

Let the level of significance $\alpha =0.10$

Since, the population standard deviation for both the group is known , even though the sample size is less than 30 , use z test

The test statistic is

$z=\frac{\bar x_1 - \bar x_2}{\sqrt{\frac{\mu_1^2}{n_1} +\frac{\mu_2^2}{n_2} } }$

The sample mean for the DH group is computed as

$\bar x_1=\frac{1}{n_1} \sum_{i=1}^{n_1}\\\\=\frac{1}{20} (0+6+8+2+2+4+7+7+6+5+1+1+5+4+4+5+7+11+10+0)\\\\=\frac{92}{20}\\\\=4.6$

The sample mean of no DH is computed as

$\bar x_2=\frac{1}{n_2} \sum_{i=1}^{n_1}\\\\=\frac{1}{20} (3+6+2+4+0+5+7+6+1+8+12+4+6+3+4+0+5+2+1+4)\\\\=\frac{83}{20}\\\\=4.15$

The test statistic is

$z=\frac{\bar x_1 - \bar x_2}{\sqrt{\frac{\mu_1^2}{n_1} +\frac{\mu_2^2}{n_2} } }$

$=\frac{4.60-4.15}{\sqrt{\frac{2.54^2}{20} +\frac{2.54^2}{20} } } \\\\=\frac{0.45}{\sqrt{0.32258+0.32258} } \\\\=\frac{0.45}{0.803219}\\\\=0.5602$

P-Value

From the alternative hypothesis, it is clear that the test is one tailed test

P-value = P(Z > z)

$1-P(Z\leq z)\\\\1-P(Z\leq 0.5602)$

1 - normsdist (0.5602)

(using excel function "normsdist(z)")

= 1 - 0.7123

= 0.2877

Therefore, the P-Value is 0.2877

Decision Rule

Reject the null hypothesis , if the p-value is less than the level of significance . that is p-value is < 0.10

Here, the p-value is 0.2877 which is greater than the level of significance 0.10

so , fail to reject the null hypothesis and conclude that there is no sufficient evidence to support the claim that more runs scored in games for which DH is used.

Answer:

423.9

Step-by-step explanation:

Area 1 = 3.14 (16²) = 803.84

Area 2 = 3.14 (11²) = 379.94

803.84 - 379.94 = 423.9

Help me!!! please!!!

Step-by-step explanation:

I guess it means we need to calculate the height of the green dot on the bicycle wheel that moves as the wheel turns by a certain radial distance.

since the circumference of a circle is 2×pi×r, the circumference for a circle with radius = 1 is simply 2×pi (ft in this case).

pi/2 = 90° or a quarter rotation.

pi = 180° or a half rotation.

3×pi/2 = 270° or 3 quarter rotation.

2×pi = 360° or a full rotation.

the height starts at 6ft, and can go up 2 more ft (the diameter of the wheel) to 8 ft.

so, the table is

0 6

pi/2 7 (6+1)

pi 8 (6+2)

3×pi/2 7 (6+2-1)

2×pi 6 (6+2-2) back to the starting height

so,

a = 6

b = 7

c = 8

d = 7

e = 6
