Answer:

144.

Step-by-step explanation:

Sum of n terms = (n/2)[a1 + l]    where a1 = first and l = last term.

There are ( 1 + 23) / 2 = 12 terms in this series.

So  the sum = (12/2) [ 1 + 23]

= 6 * 24

= 144.

1. -1/5>-3/5 because we have like denominators we compare the inputs by the numerators.

2. 3/4 > 5/8 the least common denominator is: 8

Rewriting as equivalent fractions with the LCD:

                                   3/4 = 6/8    5/8 = 5/8

Comparing the numerators of the equivalent fractions we have:

disa [49]

Answer:

There is sufficient evidence. A further explanation is provided below.

Step-by-step explanation:

According to the question,

The alternative as well as null hypothesis will be:

H_0:\mu = 16

H_a:\mu>16

The test statistics will be:

⇒ z = \frac{\frac{\bar x - \mu}{\sigma} }{\sqrt{n} }

By putting the values, we get

⇒    =\frac{\frac{16.06-16}{0.24} }{\sqrt{96} }

⇒    =\frac{\frac{0.06}{0.24} }{\sqrt{96} }

⇒    =2.45

Or,

The p-value will be:

= 0.0071

i.e.,

⇒ p-value< \alpha

Thus the above is the correct answer.
