Answer:

Pat weigh in 4 years

Step-by-step explanation:

Consider the provided information.

Your friend Pat says to you, "I'm on a new diet plan and I've been able to lose about a pound a week."

We need to find how much would Pat weigh in 4 years.

Let say there are 52 weeks in a year.

So in 4 years there will be;

52×4 = 208 weeks

Your friend Pat lose about a pound a week.

Thus, the 208 weeks he will lose around 208 pounds.

Pat currently weighs 220 pounds

220-208 = 12 pounds

Hence, Pat weigh in 4 years will be 12 pounds.

Iron deficiency anemia is an important nutritional health problem in the U.S. A dietary assessment was performed on 51 boys 9-11
Bond [772]

Answer:

a) Null hypothesis:\mu = 14.44    

Alternative hypothesis:\mu \neq 14.44    

b) t=\frac{12.50-14.44}{\frac{4.75}{\sqrt{51}}}=-2.917    

The degrees of freedom are given by:

df =n-1= 51-1=50

Now we can calculate the p value taking in count the alternative hypothesis

p_v =2*P(t_{50}

Since the p value is lower than the significance \alpha=0.05 we have enough evidence to reject the null hypothesis and the true mean is significantly different from 14.44

c) 12.50 -2.01 \frac{4.75}{\sqrt{51}}= 11.163

12.50 +2.01 \frac{4.75}{\sqrt{51}}= 13.837

Step-by-step explanation:

Information given

\bar X=12.50 represent the mean for the daily iron intake

s=4.75 represent the sample deviation

n=51 sample size    

\mu_o =14.44 represent the reference value  

\alpha=0.05 represent the significance level for the hypothesis test.  

t would represent the statistic

p_v represent the p value for the test

Part a

We want to test if the mean iron intake among the low-income group is different from that of the general population, the system of hypothesis would be:    

Null hypothesis:\mu = 14.44    

Alternative hypothesis:\mu \neq 14.44  

Part b  

Since we don't know the population deviation the statistic would be given by:

t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}} (1)    

Replacing the info we got

t=\frac{12.50-14.44}{\frac{4.75}{\sqrt{51}}}=-2.917    

The degrees of freedom are given by:

df =n-1= 51-1=50

Now we can calculate the p value taking in count the alternative hypothesis

p_v =2*P(t_{50}

Since the p value is lower than the significance \alpha=0.05 we have enough evidence to reject the null hypothesis and the true mean is significantly different from 14.44

Part c

The confidence interval would be given by:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}

For the 95% confidence interval we can find the critical value in a t distribution with 50 degrees of freedom and we got:

t_{\alpha/2}= 2.01

And replacing we got:

12.50 -2.01 \frac{4.75}{\sqrt{51}}= 11.163

12.50 +2.01 \frac{4.75}{\sqrt{51}}= 13.837

The answer is $240.

If you round each amount to the nearest ten you get $130.00, $60.00, and 50.00. When you add all of those together you get an estimated amount of $240.
