For 100 births, P(exactly 55 girls = 0.0485 and P (55 or more girls)= 0.184 - screenshot listed belowThe relevant probability is (P exactly 55 girls) , (P 55 or more girls) so 55 girls in 100 births (is, is not) a significantly high number of girls because the relevant probability is (greater than, less than , or equal to).

According to a survey in a country, 17% of adults do not own a credit card. Suppose a simple random sample of 400 adults is obtained. Complete parts (a) through (d) below.(a) Describe the sampling distribution of ModifyingAbove p with caret, the sample proportion of adults who do not own a credit card. Choose the phrase that best describes the shape of the sampling distribution of ModifyingAbove p with caret below. A. Not normal because n less than or equals 0.05 Upper N and np left parenthesis 1 minus p right parenthesis greater than or equals 10 B. Approximately normal because n less than or equals 0.05 Upper N and np left parenthesis 1 minus p right parenthesis greater than or equals 10 C. Not normal because n less than or equals 0.05 Upper N and np left parenthesis 1 minus p right parenthesis less than 10 D. Approximately normal because n less than or equals 0.05 Upper N and np left parenthesis 1 minus p right parenthesis less than 10 Determine the mean of the sampling distribution of ModifyingAbove p with caret. mu Subscript ModifyingAbove p with caret Baseline equals nothing (Round to two decimal places as needed.) Determine the standard deviation of the sampling distribution of ModifyingAbove p with caret. sigma Subscript ModifyingAbove p with caretequals nothing (Round to three decimal places as needed.)(b) What is the probability that in a random sample of 400 adults, more than 21% do not own a credit card? The probability is nothing.(Round to four decimal places as needed.) Interpret this probability. If 100 different random samples of 400 adults were obtained, one would expect nothing to result in more than 21% not owning a credit card.(Round to the nearest integer as needed.)(c) What is the probability that in a random sample of 400 adults, between 16% and 21% do not own a credit card? The probability is nothing.(Round to four decimal places as needed.) Interpret this probability. If 100 different random samples of 400 adults were obtained, one would expect nothing to result in between 16% and 21% not owning a credit card.(Round to the nearest integer as needed.)(d) Would it be unusual for a random sample of 400 adults to result in 64 or fewer who do not own a credit card? Why? Select the correct choice below and fill in the answer box to complete your choice.(Round to four decimal places as needed.) A. The result is not unusual because the probability that ModifyingAbove p with caret is less than or equal to the sample proportion is nothing, which is greater than 5%. B. The result is unusual because the probability that ModifyingAbove p with caret is less than or equal to the sample proportion is nothing, which is greater than 5%. C. The result is not unusual because the probability that ModifyingAbove p with caret is less than or equal to the sample proportion is nothing, which is less than 5%. D. The result is unusual because the probability that ModifyingAbove p with caret is less than or equal to the sample proportion is nothing, which is less than 5%. … read more
