A physiologist believes he has discovered a new steroid hormone that can control the blood glucose in mammals. In an experiment
Marta_Voda [28]

Answer:

1.) One sample t test

2.) New steroid does not decrease blood glucose level in rats ; H0 : μ = 31

3.) New steroid does blood glucose level in rats ; H1 : μ ≠ 31

4.) 2.718

5.) 3.36

Step-by-step explanation:

We only have one sample; hence, we use an independent sample t test.

Given the sample data :

X : 35,36,37,33,34,35,33,35,37,36,34,35

Using calculator;

Sample mean, Xbar = 35

Null hypothesis ;supports that the mean glucose level of species equals ; H0 : μ = 31

The alternative hypothesis ; H1 negates the null hypothesis and aligns with the sample mean ; 35 > 31 ;

H1 : μ > 31

The critical value can be obtained from the T-distribution table ;

α = 0.01 ; degree of freedom, df = n - 1 = 12 - 1 = 11

Tcritical value = 2.718

Tstatistic : (xbar - μ) ÷ (s/√n)

Tstatistic = (35 - 31) ÷ (4.12/√12)

Tstatistic = 3.36

Tstatistic is more extreme Than the critical value

Drag the numbers to the boxes to order them from least to greatest value.
attashe74 [19]
Hello!

First you have to convert them all into numbers

2 = 2
47/14 = 3.35
sqrt of 5 = 2.23
0.9 = 0.9
0 = 0

Now you list them from least to greatest

The answer is 0, 0.9, 2,  \sqrt{5} ,  \frac{47}{14}

Hope this helps!
