A study published in Psychiatry Research states that 62% of autistic children are left-handed.[12] A local resource for children with autism, Central Coast Autism Learning Partners, is curious to see
if their set of autistic children show a similar proportion of being left-handed. When a random
sample of 26 autistic children were observed, 17 were found to be left-handed. Is there enough
statistical evidence based on the sample to dispute the results of the study published in Psychiatry
Research? Use the P-value method and let
a=.05.

Determine the mean and variance of the random variable with the following probability mass function. f(x)=( 729divided by 91) (1 divided by 9) superscript x baseline comma x equals 1,2,3 round your answers to three decimal places (e.g. 98.765).

41/17 as a decimal rounded to the nearest hundredth

Naruto is choosing between two venues that will deliver food to his house. with probability 1/3 he will choose ramen mania (r), and with probability 2/3 he will choose sushi (s). if he chooses r, 15 minutes after making the call, the remaining time it takes the food to arrive is exponentially distributed with average 10 minutes. if he orders s, 10 minutes after making the call, the time it takes the food to arrive is exponentially distributed with an average of 12 minutes. given that he has already waited 25 minutes after calling, and the food has not arrived, what is the probability that he ordered from r? i am really stuck on how to set this up, so if you could be extra clear, that would be super ! in advance
