At an early stage of clinical trials of a certain method of gender selection, 15 couples using that method gave birth to 1 girl and 14 boys. Comp a. Assuming that the method has no effect and boys and girls are equally likely, use the range rule of thumb to identify the limits separating va Based on the results, is the result of 1 girl significantly low? Significantly low values for the number of girls in 15 births are 3.6 and lower. Significantly high values for the number of girls in 15 births are (Type integers or decimals rounded to one decimal place as needed.) b. Find the probability of exactly 1 girl in 15 births, assuming that the method has no effect. 0.000458 (Type an integer or decimal rounded to six decimal places as needed.) c. Find the probability of 1 or fewer girls in 15 births, assuming that the method has no effect. (Type an integer or decimal rounded to six decimal places as needed.)
