Does the decimal equivalent of p/q, where p and q are positive integers, contain only a finite number of nonzero digits?

Aleks [24]

A/B is a reduced fraction which can be represented as a terminating decimal if and only b is of the form 2^n5^n where m and n are non negative integers. For example: 7/250, the terminating decimal here is 0.028 as 250 as the denominator equals to 2*5^2.

According to the above, we must know whether the denominator have only 2-s and or 5-s as the prime factors. So,

Q = 8 = 2 ^3 = hence the denominator has only 2 prime factors. Fraction P/Q will be termed as terminated decimal which is sufficient.

A student wanted to construct a 95% confidence interval for the mean age of students in her statistics class. She randomly selec

Alex_Xolod [135]

Answer:

95% confidence interval for the population mean is 20.255 and 17.945

Step-by-step explanation:

given data

mean = 19.1

standard deviation = 1.5

n = 9

to find out

95% confidence interval for the population mean

solution

we know 95% confidence interval formula i.e.

mean +/- t * standard deviation/ $\sqrt{n}$ .............1

here t for 9 students 2.31 ( from t table)

so put all value n t standard deviation and mean in equation 1

= mean +/- t * standard deviation/ $\sqrt{n}$

= 19.1 +/- 2.31 * 1.5/ $\sqrt{9}$

= 20.255 and 17.945

95% confidence interval for the population mean is 20.255 and 17.945
