What is the P(−2.4

Fill in the blanks to complete the following statements. (a) For the shape of the distribution of the sample proportion to be approximately normal, it is required that np(1-p) ≥_ (b) Suppose the proportion of a population that has a certain characteristic is 0.5. The mean of the sampling distribution of p from this population is µ = Hp (This is a reading assessment question. Be certain of your answer because you only get one attempt on this question.) (a) For the shape of the distribution of the sample proportion to be approximately normal, it is required that np(1 − p)≥| (Type an integer or a decimal.) (b) Suppose the proportion of a population that has a certain characteristic is 0.5. The mean of the sampling distribution of p from this population is μ = (Type an integer or a decimal.) р

Test the claim that the proportion of people who own cats is smaller than 70% at the 0.10 significance level. Based on a sample of 600 people, 61% owned catsThe p-value is:  (to 2 decimals)

Suppose it is known that the proportion of students at a local high school that take public transit to school is p = 0.15. 5. If a sample of n = 86 students were taken randomly from the school, describe the distribution of the sample proportion, p. Make sure to verify the conditions required to make your calculations and show all work.

A manufacturer makes thousands of ballpoint pens per day, and estimates that 3% are defective and must be discarded. The manufacturer decides to do a random sample of 350 pens per day to check for quality control.   e. Compute the range of usual values for x. Show all work. f. Would it be unusual for the sample of 350 to have 20 defective pens?

A researcher reports t(22) = 5.30, p < .01 for an independent measures experiment. how many individuals participated in the entire experiment?

Solve the 2nd question please

Plzzz explain.

9.4 Differences between Proportions

A personality test has a subsection designed to assess the "honesty" of the test-taker. Suppose that you're interested in the mean score, μ, on this subsection among the general population. You decide that you'll use the mean of a random sample of scores on this subsection to estimate μ. What is the minimum sample size needed in order for you to be 95% confident that your estimate is within 2 of μ? Use the value 22  for the population standard deviation of scores on this subsection. Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements).
