This Question: 1 pt This Test: 30 pts possib The accompanying table describes results from groups of 8 births from 8 derent sets of parents. The random variable x represents the number of girls among&chilidren; Complete parts (a) through )bw EE Click the icon to view the table. a. Find the probability of getting exactly 1 girl in 8 births (Type an integer or a decinal. Do not round.) b. Find the probability of getting 1 or fewer girls in 8 bierths for x CType an nteger or a decimal. Do not round.) c. Which probablity is relevant for determining whether 1 is a sgnhanty low number of gris in 8 brtsthe resut tom partor part or? probably Srce getting Oghts is an even lower number of gris tan gettng 1 get the res O C. Since the probwbility d. ls 1 a significanty low number of giis in 8 births? Why or why not? Use 005 as the threshoid for a significant event OA. t from patb) isthe relevant relevant probability O B. Since the probability of getting 0 girts is less likely than getting 1 gir, the resulit from part (a) is the O D. Since the probability of getting more than 1 git is the complement of the resut from part (o t of getting 1 gin is the resulit from part (a), this is the elevant probability this is the relevant probabiy O B. No, since the appropriate probablity is less than 0.05, ia is not a signficanty low number OC, Yos. since the o. Yes, sncn the approprato probabitysless than 0 05, it is a signfanty low number. is greater than 005, t is a

Explanation / Answer

Answer in detail, with explanation below:

a. For this use the table and refer to X=1, and the probability related to that. P(X=1) = .034
b. this is to find the cumulative probability till X = 1, therefore : P(X<=1) = P(X=0)+P(X=1) = .002+.034 = .036
c. C is right, P(X=1) alone is the sole decider of wether 1 is a significantly low number of girls in 8 births
d. Yes. P(X=1) = .034 which is less than .05. Here, anything less than .05 is insignificant. So, D is right
