Eric randomly surveyed 150 adults from a certain city and asked which team in a contest they were rooting for, either North Hig

Romashka-Z-Leto [24]

Answer:

B

Step-by-step explanation:

A 95% confidence level interval will have 0.52 (lower interval) & 0.68 (upper interval) which means that that if 90 individuals root for North HS then p value is 0.6 which will fall in the 95% confidence interval range.
For the option B the p value will also be same as in case A hence B is true as an alternative hypothesis.
We can calculate P value

Confidence Interval = p ± z $\sqrt{p(1-p)/n}$

Answer:

D 6

Step-by-step explanation:

Normally when I multiply mixed numbers, I change them to improper fractions first so that it is easier.

1 $\frac{2}{10}$ × 5 = $\frac{12}{10}$ × 5

Multiply 5 by the numerator of the fraction and leave the denominator alone.

$\frac{12}{10}$ × 5 = $\frac{60}{10}$

Change back to simplest form.

$\frac{60}{10}$ = 6
