Brown tree snakes are an invasive species causing huge environmental and financial damage in Guam. Researchers captured brown tr

ee snakes on Guam's Andersen Air Force Base, and a random sample of 250 of these snakes were weighed. The researchers want to perform a hypothesis test to see if the mean weight of a brown tree snake in Guam is significantly greater than 120 grams.
Set up the appropriate null and alternate hypotheses for the test.

Answer:

Null Hypothesis, H_0 : \mu \leq 120 grams

Alternate Hypothesis, H_A : \mu > 120 grams

Step-by-step explanation:

We are given that researchers captured brown tree snakes on Guam's Andersen Air Force Base, and a random sample of 250 of these snakes were weighed.

The researchers want to perform a hypothesis test to see if the mean weight of a brown tree snake in Guam is significantly greater than 120 grams.

<u><em>Let </em></u>\mu<u><em> = mean weight of a brown tree snake in Guam.</em></u>

So, Null Hypothesis, H_0 : \mu \leq 120 grams

Alternate Hypothesis, H_A : \mu > 120 grams

Here, <u>null hypothesis states that</u> the mean weight of a brown tree snake in Guam is smaller than or equal to 120 grams.

On the other hand, <u>alternate hypothesis states that</u> the mean weight of a brown tree snake in Guam is significantly greater than 120 grams.

So, this would be the appropriate null and the alternative hypothesis to test this claim.

5. A study found that the average time it took a person to find their dream home was 5.9 months. If a sample of
solong [7]

Answer:

The 95% confidence interval of the mean time it took a person to find their dream home is between 5.64 months and 6.16 months.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.025 = 0.975, so z = 1.96

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.96\frac{0.8}{\sqrt{36}} = 0.26

The lower end of the interval is the sample mean subtracted by M. So it is 5.9 - 0.26 = 5.64 months

The upper end of the interval is the sample mean added to M. So it is 5.9 + 0.26 = 6.16 months.

The 95% confidence interval of the mean time it took a person to find their dream home is between 5.64 months and 6.16 months.

Pie Chart 3: Drinking Water Services (of 7.8 Billion People)
bija089 [108]

Answer:

access to safe drinking water is a fundamental need and human right. Securing access for all would go a long way in reducing illness and death, especially among children. “Safely managed” drinking water services represent an ambitious new rung on the ladder used to track progress on drinking water.  Since 2000, 2 billion people have gained access to safely managed services (i.e., accessible on-premises, available when needed, and free from contamination). In 2020, 5.8 billion people used safely managed services and a further 2 billion people  used basic services ( improved sources within 30 minutes per round trip to collect water).

However, 771 million people still lacked even a basic level of service, including 282 who used a “limited” water service (improved source from which water collection exceeds 30 minutes), 367 million who used unimproved sources and 122 million who still collected drinking water directly from rivers, lakes, and other surface water sources. The data reveal pronounced disparities, with the poorest and those living in rural areas least likely to use a basic service. In most countries, the burden of water collection continues to fall mainly to women and girls.

A number divided by 58 is close to 30.
Rom4ik [11]
X/58 (is roughly) 30
x/58 = 30
Multiply 58 on both sides.
x = 1,740

So it has to be c. 1,843
