Assume that we want to construct a confidence interval. do one of the following, as appropriate: (a) find the critical value t subscript alpha divided by 2tα/2, (b) find the critical value z subscript alpha divided by 2zα/2, or (c) state that neither the normal distribution nor the t distribution applies. here are summary statistics for randomly selected weights of newborn girls: nequals=182, x overbarxequals=32.9 hg, sequals=6.6 hg. the confidence level is 90%. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
