QUESTION 1 The Childhood Autism Rating Scales (CARS), for the population at large, has a mean of 33. A social worker is interested in knowing whether a new
therapy technique employed with Autistic Children lowers their scores on the CARS. She takes a random sample of 11 children with Autism, has them
undergo the new therapy technique for three months, and finds their scores to be the following on the CARS: 32.01, 33.22. 30.99, 31.64, 33, 32.50,
33.67.33.11, 31.54, 31.99.32. Test the null hypothesis at the .01 level of significance.

answer: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
