Pedro thinks that he has a special relationship with the number 3. In particular, Pedro thinks that he would roll a 3 with a fai

anyanavicka [17]

Answer:

p value = 0.3122

Step-by-step explanation:

Given that Pedro thinks that he has a special relationship with the number 3. In particular,

Normally for a die to show 3, probability p = $\frac{1}{6} =0.1667$

Or proportion p = 0.1667

Pedro claims that this probability is more than 0.1667

$H_0 = P =0.1667______H_a = P>0.1667_____$

where P is the sample proportion.

b) n=30 and $P = 6/30 =0.20$

Mean difference = $0.2-0.1667=0.0333$

Std error for proportion = $\sqrt{\frac{p(1-p)}{n} } \\=0.0681$

Test statistic Z = p difference/std error = 0.4894

p value = 0.3122

p >0.05

So not significant difference between the two proportions.

An area of 3.5m² is the same as 350000mm². True or false. Justify your answer

Vsevolod [243]

No, because to convert meter to millimeter you'll have to multiply the length value by 1000 which will give you 3500.

3.5 × 1000

= 3500.

have a great day!
