Consider testing the hypothesis H0: mu= 800 vs. H1: mu not identical to800. If the value of the test statistic z equals 1.75, th

Brums [2.3K]

Answer:

0.0802

Step-by-step explanation:

Calculation for the p-value

Based on the information given this is a two tailed test

Hence,

p(z< -1.75)= 0.0401

p(z> 1.75) = 0.0401

Now let calculate the p-value

p-value=2* 0.0401

p-value= 0.0802

Therefore If the value of the test statistic z equals 1.75 the p-value will be 0.0802

Mazyrski [523]

Mumbi is approximately 845 kilometers away from Bangalore, and Mumbai is approximately 1160 km away from Delhi, then the ratio between these distances is

$\dfrac{845}{1160}=\dfrac{169}{232}.$

A. Bangalore to Mumbai: 116.5 cm;

Mumbai to Delhi: 174 cm

The ratio:

$\dfrac{116.5}{174}=\dfrac{233}{348}\neq \dfrac{169}{232}$

This option is false.

B. Bangalore to Mumbai: 42.25

Mumbai to Delhi: 58 cm

The ratio is

$\dfrac{42.25}{58}=\dfrac{845}{1160}=\dfrac{169}{232}$

This option is true.

C. Bangalore to Mumbai: 23.4 cm

Mumbai to Delhi: 29 cm

The ratio is

$\dfrac{23.4}{29}=\dfrac{117}{145}\neq \dfrac{169}{232}$

This option is false.

D. Bangalore to Mumbai: 16.9 cm

Mumbai to Delhi: 23.2 cm

The ratio is

$\dfrac{16.9}{23.2}=\dfrac{169}{232}$

This option is true.

E. Bangalore to Mumbai: 25.35 cm

Mumbai to Delhi: 34.8cm

The ratio is

$\dfrac{25.35}{34.8}=\dfrac{507}{696}=\dfrac{169}{232}$

This option is true.

Ronald works in an Ornithology (bird maintenance) department. Students asked him to find out the best estimate of the local bird

djyliett [7]

Answer:

618 birds.

Step-by-step explanation:

Let the estimated number of birds=x

Out of x birds, he tied a belt around the legs of 40 birds.

When he observed 520 birds, 34 of which had belts.

Expressing each as a ratio

$\frac{x}{40}=\frac{520}{34}$

Cross Multiply

34x=520X40

x=520X40÷34=611.7≈618

There are an estimated 618 birds.
