The world's population is expected to grow at a rate of 1.3% per year until at least the year 2020. In 1994 the total population
Marina CMI [18]
The solution to your problem is as follows:

Given: 
P₀ = 5,642×10^6 people, 
i = 1.3% = 0.013 per year, 
n = 2020 - 1994 = 26 years, 

We get: 
<span>
Pn = P₀ e^(i.n) </span>
. . .= 5,642×10^6×e^(0.013×26) 
<span>. . .= 7,911×10^6 people

Therefore, the </span>the world's predicted population in the year 2020 is <span>7,911×10^6 people.

Unlike most packaged food products, alcohol beverage container labels are not required to show calorie or nutrient content. An a
zhenek [66]

Answer:

We conclude that the true average estimated calorie content in the population sampled exceeds the actual content.

Step-by-step explanation:

We are given that an article reported on a pilot study in which each of 58 individuals in a sample was asked to estimate the calorie content of a 12 oz can of beer known to contain 153 calories.

The resulting sample mean estimated calorie level was 193 and the sample standard deviation was 88.

Let \mu = <u><em>true average estimated calorie content in the population sampled.</em></u>

So, Null Hypothesis, H_0 : \mu \leq 153 calories     {means that the true average estimated calorie content in the population sampled does not exceeds the actual content}

Alternate Hypothesis, H_A : \mu > 153 calories     {means that the true average estimated calorie content in the population sampled exceeds the actual content}

The test statistics that would be used here <u>One-sample t test statistics</u> as we don't know about the population standard deviation;

                             T.S. =  \frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }  ~ t_n_-_1

where, \bar X = sample mean estimated calorie level = 193 calories

            s = sample standard deviation = 88

            n = sample of individuals = 58

So, <u><em>the test statistics</em></u>  =  \frac{193-153}{\frac{88}{\sqrt{58} } }  ~ t_5_7

                                       =  3.462

The value of t test statistics is 3.462.

Since, in the question we are not given the level of significance so we assume it to be 5%. <u>Now, at 0.05 significance level the t table gives critical value of 1.6725 at 57 degree of freedom for right-tailed test.</u>

Since our test statistic is more than the critical value of t as 3.462 > 1.6725, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region due to which <u>we reject our null hypothesis</u>.

Therefore, we conclude that the true average estimated calorie content in the population sampled exceeds the actual content.
