Hi could you answer the wrong problems

In a distribution with M = 3.40, SD = 1.47, what proportion of values are above x = 3.00?   In a distribution with M = 3.40, SD = 1.47, what X values marks the middle 50% of the distribution?

You are testing the claim that the proportion of men who own cats is smaller than the proportion of women who own cats.You sample 110 men, and 90% own cats.You sample 90 women, and 20% own cats.Find the proportion of the pooled samples, (pcpc), as a decimal, rounded to two decimal places.

Which z-score has the higher frequency? (a) z = +1.0 or z = +2.3; (b) z = −2.8 or z = −1.7; (c) z = −.70 or z = −.20; (d) z = 0.0 or z = −2.0.

A medical researcher tested a new treatment for poison ivy against the traditional ointment. He concluded that the new treatment is more effective. Explain what the P-value of 0.037 means in this context. Explain what the P-value of 0.037 means in this context. O A. There is a 3.7% difference between the effectiveness of the new treatment and the effectiveness of the traditional ointment. O B. If there is no difference in effectiveness, the chance of seeing an observed difference this large or larger is 3.7% by natural sampling variation. O C. If there is a difference in effectiveness, the chance of seeing an observed difference this large or larger is 3.7% by natural sampling variation. D. There is a 3.7% chance that the new treatment is effective.

your car is more crowded than you think.  table 5.8 reports results from a 1969 personal transportation survey on "home-to-work" trips in metropolitan areas. The survey stated that the average car occupancy was 1.4 people. check that calculation.
