For 100 births, P(exactly 56 girls = 0.0390 and P 56 or more girls = 0.136. Is 56 girls in 100 births a significantly high number of girls? Which probability is relevant to answering that question? Consider a number of girls to be significantly high if the appropriate probability is 0.05 or less V so 56 girls in 100 birthsa significantly high number of girls because the relevant probability is The relevant probability is 0.05 IS

The relevant probability is P(56 or more girls).

56 girls in 100 births is not a significantly high number of girls.

Step-by-step explanation:

To evaluate if 56 girls in 100 births a significantly high number of girls we must look at the cumulative probability of 56 girls or more in 100 births (P(n≥56)=0.136). The probability of exactly 56 girls is not particularly relevant since it represents only 1 of 100 possible outcomes and thus its likelihood is quite low, the higher the number of outcomes the less significant the probability of a single outcome occurring becomes.

Since the relevant probability is higher than 0.05, (0.136 > 0.05), 56 girls in 100 births is not a significantly high number of girls.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
