The mean sat score in mathematics, μ , is 534 . the standard deviation of these scores is 25 . a special preparation course claims that its graduates will score higher, on average, than the mean score 534 . a random sample of 37 students completed the course, and their mean sat score in mathematics was 535 . assume that the population is normally distributed. at the 0.05 level of significance, can we conclude that the preparation course does what it claims? assume that the standard deviation of the scores of course graduates is also 25 . perform a one-tailed test. then fill in the table below. carry your intermediate computations to at least three decimal places, and round your responses as specified in the table. (if necessary, consult a list of formulas.) the null hypothesis: h0: the alternative hypothesis: h1: the type of test statistic: the value of the test statistic: (round to at least three decimal places.) the critical value at the 0.05 level of significance: (round to at least three decimal places.) can we support the preparation course's claim that its graduates score higher in sat? yesno μσpxsp

Guys i need ! graded assignment grade 8 checkpoint 2, part 2 answer the questions below. when you are finished, submit this assignment to your teacher by the due date for full credit. total score: of 9 points (score for question 1: of 4 points) 1. the cost of renting a car for a day is $0.50 per mile plus a $15 flat fee. (a) write an equation to represent this relationship. let x be the number of miles driven and y be the total cost for the day. (b) what does the graph of this equation form on a coordinate plane? explain. (c) what is the slope and the y-intercept of the graph of the relationship? explain.

The description below represents function a and the table represents function b: function a the function is 5 more than 3 times x. function b x y −1 2 0 5 1 8 which statement is correct about the slope and y-intercept of the two functions? (1 point) their slopes are equal but y-intercepts are not equal. their slopes are not equal but y-intercepts are equal. both slopes and y intercepts are equal. neither slopes nor y-intercepts are equal.
