Question

need help explaining part n and o please!

Proportions of samples 357/1000 = 0.3570 (m) Now what are the most common outcomes for "number of heads" in your dotplot? Is this what you would expect? Explain why or why not. >> According to the dot plot above, the most common outcome for number of heads is 13. Yes, this is what I expect because my probability of .80 seems to create a normally distributed graph. (n) From this p-value, what conclusion would you come to in this study - Does .80 appear to be a reasonable guess for the probability an infant in general will choose the helper toy? Explain your reasoning behind your conclusion as before. (o) Based on these analyses, which guess for the underlying probability, .5 or .8, appears more reasonable based on the data collected by these researchers? Explain.

Explanation / Answer

n) If you use the one proportion z test H0: p=0.80 vs Ha:p not equal 0.80 and p^=0.3570

then you get p value=0 so we reject the null hypothesis

conclusion : 0.80 is not reasonable guess for the probability an infant in general we choose the helper toy.

o)

From this analysis 0.5 is better reasonable based on the data . because probability of head is 0.5 so its appear more reasonable based on the data collected by these researchers.
