Use the ALEKS calculator to solve the following problems. (a) Consider at distribution with 19 degrees of freedom. Compute P (t≤1.29). Round your answer to at least three decimal places. P(t≤1.29)= (b) Consider a t distribution with 15 degrees of freedom. Find the value of c such that P(-c

Suppose that scores on a particular test are normally distributed with a mean of 140 and a standard deviation of 18. What is the minimum score needed to be in the top 10% of the scores on the test? Carry your intermedlate computations to.at least four decimal places, and round your answer to one decimal place. Continue ace esc & # 24 @ 7 4 2 t y r e

Stoaches are fictional creatures, sometimes mistaken for mome raths. Suppose a two-tailed t-test is conducted to test for a difference between the population means of adult female stoach weights and adult male stoach weights. The female sample has 13 weights, and the male sample has 7 weights. The t-statistic for the test is -0.20542. What is the p-value? (Give your answer to 4 decimal places.) p-value:

t has been suggested that gossiping about others may affect how likeable you are. Two groups of participants are asked to read a vignette describing a fictional person. They are then asked to rate how much they would like the person described in the vignette on a continuous scale from 1-15, where higher scores represent a higher likability. The first group of participants (n=20) reads a vignette describing a person that frequently gossips and obtains an average likability score of (M1) with a variance of (S12). The second group of different participants (n=20) reads a vignette describing a person that never gossips and obtains an average likability score of (M2) with a variance of (S22). Given that there is not much research in this area, test the hypothesis that gossiping impacts likability at an alpha=0.05.  1, Are the results you obtained meaningful? report the results here for your effect size showing all your work and your interpretation  2.
