To solve this, we take the number of subjects who weren't diabetic, and then divide them by the total number of subjects who took the test:

Probability = $\frac{28}{3+28}$
= $\frac{28}{31}$
= 0.903225..
= 0.90 (rounded)
-------------------------------------------------------------------------------------------------------------
Answer:

So the probability of randomly selecting a subject who was not diabetic would be <u></u>0.90 (the final option)

-------------------------------------------------------------------------------------------------------------
<em>Note:
</em> <em>We only used the numbers under 'Negative Test', because the question wanted the probability 'given that the test result was negative'</em>

Descent, Inc., produces a variety of climbing and mountaineering equipment. One of its products is a traditional three-strand cl

Rainbow [258]

Solution :

Assuming $\sigma_1^2=\sigma_2^2$

We have to test

$H_0:\mu_1=\mu_2$

Against $H_a: \mu_1 \neq \mu_2$

Level of significance, $\alpha = 0.05$

$s_p=\sqrt{\frac{(n_1-1)s_1^2+ (n_2-1)s_2^2}{n_1+n_2-2}}$

$s_p=\sqrt{\frac{(25-1)(425)^2+ (20-1)(415)^2}{25+20-2}}$

= 420.6107

Under $H_0$ , the t-statistics is as follows:

$t=\frac{(\overline{x_1} - \overline{x_2})}{s_p\sqrt{\frac{1}{n_1}+\frac{1}{n_2}}} \sim$ $\text{t with }(n_1+n_2-2) \ DF$

$t=\frac{(7200-7087)}{(420.6107)\sqrt{\frac{1}{25}+\frac{1}{20}}}$

= 0.90

DF = (25 + 20 - 2)

= 43

P-value of the test = 0.375

Since the p value is more than 0.05, we fail to reject our null hypothesis.

There is no difference between then mean tensile strength of the ropes that is produced in the Bozeman and Challis.

Does the table describe x as a function of y?

kicyunya [14]

Answer:

C. No, more than one output value x is assigned to the input y-value

Step-by-step explanation:

Given

х у

-3 -2

3 6

0 7

1 7

2 4

3 - 1

Required

State if the table shows x as a function of y

x being a function of y means

$x = f(y)$

i.e. x represents the output while y represents the input of the function

Note that each value of y (input) must be assigned to separate values of x (output) for a function to be established

Having said;

Next step: We have to examine the x and y column

In the y column, the value 7 occurred twice (as shown below)

<em>х у </em>

<em>0 7 </em>

<em>1 7 </em>

<em />

This implies that;

Input 7 gives output of 0 and 1.

<em>Hence, this is not a function.</em>

<em>Option C answers the question.</em>
