A child development researcher is testing the claim that the median number of words that a 3 year old knows is 200 or more.
A child development researcher is testing the claim that the median number of words that a 3 year old knows is 200 or more. A sample of 15 children is taken and the follwing vocabulary sizes are computed: vocab size 206 244 179 316 227 176 319 141 195 260 2441 228 125 190 310 What would the null hypothesis be (use 6 for the population median) Ho: Select an answer H: Select an answer If the population median is 200, what distribution should be used to model the number of vocab sizes below 200? Select an answer - 260 244 228 125 190 310 What would the null hypothesis be (use 0 for the population median). Ho: Select an answer H: Select an answer t If the population median is 200, what distribution should be used to model the number of vocab sizes below 200? Select an answer How many observed vocabulary sizes are less than 200 (S)? Assuming the null hypothesis were true, would it be more unlikely for S to be higher than what was observed, or lower than what was observed? Select an answer What is the p-value? At a significance level of 0.05, what is your conclusion? Select an answer Submit Question
